- Let's have a look at this old 1989 Chevrolet C-4 Corvette with the 5.7 Port F.I. engine and see why the heck this thing will not start when the engine gets up to temperature. It starts out running OK but then takes a turn for the worse.

This guy is really a blessing. It's nice to watch someone who really knows what he is doing.
I have an '89 Iroc-Z with the L98 engine. I had the same problem and it turned out to be faulty injectors. There was way too much resistance for these things to fire. I got a fresh batch from injector connection and never had start issues since. Great video on how to diagnose a no start condition on an L98!
Second video I watched of this guy .... damn, he knows what he is doing and knows how to use his diagnostic equipment....he had my attention every moment - nothing boring here !!!! I would change all the injectors to be 100% I cured the problem. Very well done - didn't change a dozen parts to eventually solve the problem !!!! Great narrating too !!!!
He knows how to use his brains
This kind of diagnostic work is what EVERYONE wishes / hopes their mechanic is capable of.
However, the reality usually different.
People would gladly pay a little more to get good work like this. No doubt about it.
If you like Eric then you’ll LOVE Ivan from Pine Hollow Auto Diagnostic. He’s the king of diag
@@WifeBTR123 Yep, when I have to start making suggestions to the mechanic about what to look for, i know I'm at the wrong place.
@@WifeBTR123 XD part throwers waste ALOT of time and $$$.
32:55 that's cool how the fuel pressure reacts basically instantaneously with the throttle. Awesome video and diagnostic process! I've been learning a massive amount from your huge library of videos! I also love how even your videos from 7 years ago are still just as valuable and fun to watch as your currents ones!
It is good to see there are still technicians in the trade,and not just all parts changers.Outstanding video,i have the same year car.
very few guys in the trade care anymore .
Watching Eric always reminds me of how many tools I DON'T have.
This could be done with a multimeter, a pair of screwdrivers, and a battery. Don't let tools be what stops you.
It's not about what you have, it's about what ELSE you can have, brother.
Tools for men are like shoes for women. We gladly buy a tool that we would use once, or "it will come handy" but it never does, and ends up lying in tool drawer until it becomes obsolete...
U said it. U have never lied.
It also reminds me of how many tools I don't need because my cars are older than that and have carburetors instead of fuel injection.
I do have a timing light, vacuum gauge and a CO meter though.
Eric, love your videos. You are THE perfect mechanic. Master of mechanical AND electrical / electronic, computer and old school analogue. Great deductive and reasoning process of thought. Articulate and humorous, you put together a great video, a feat in itself. Do I sound like a fan ? You bet !
From my experience, a single shorted injector on a bank-fired PFI system will pull the entire bank down and prevent it from firing. Quite common on OBD I GMs. Interestingly, those Multec I fuel injectors that GM used, the coil is actually exposed to fuel ; they use the fuel to cool the coils. Allowing fuel to sit for a long time, or even using harsh injector cleaners, can eat through the insulating varnish on the coil wires and short the injector.
Luckily, whether by design or the limitations of the technology of the day, the injector drivers on these GM PFI systems are built like brick shithouses, and usually survive a shorted injector or two. Certainly can't say the same for these new SFI systems!
Awesome video, Eric! Great diagnostics and good process!
Yes, the Quad Driver circuits are over-amp protected by MOSFETs and heat sinks, but those can get hot, too.

are you suggesting the injectors are wired in series, or that the computer detects a fault?
@@andiarrohnds5163 L98 FINJ systems have 2 banks of 4 FINJ ea. wired in parallel. The ECM switches the ground.
Another brilliant GM design.
Eric deserves a beer and a handshake (actually an elbow bump during the corona pandemic) for the time and effort he puts in to his videos. He shows you how to go about things right, armed with knowledge and excellent equipment to logically approach the diagnosis. Fantastic presentation and explanation of how to go about tracing out the problem.
You da man. Hope you’re staying safe and healthy in NY state
someone who is getting extremely rare .
Love the diagnosis videos. You have a great logical process of diagnosing and its very entertaining and educational as a DIYer to watch a pro at work. Great video Eric!
+UserNumber809 Thanks
This exact thing happened to my 91 olds Cutlass. The mechanic didn't believe me until it left him stranded on lunch. He kept throwing parts at it, coil packs, ecm, all while trying to charge me and not solving the problem. Needless to say, this issue dissolved a long relationship i had with this mechanic. I appreciate your sense of diagnostics. You do a great job! Thank you for these videos!
Eric, Thanks for taking the time out of your busy days to make these Very interesting videos.!!! I myself is from a long line of auto Mechanic's from Shade tree to Professional... And every time i watch your video's i find them very interesting and your very thorough with your diagnosis... Thanks Again.!!! Ky Ridge Runner...
With a resistance reading that high, it's a wonder that the ECU didn't get fried from too much current draw! You are an amazing diagnostician.
resistance decreases current flow. The resistance was lower due to the shorted coil, not higher
Another excellent detailed video! The 89 Corvette used the Multec injectors (Gray colored body). The injector coils were exposed to the fuel. Eventually the insulation of the coil winding's erodes and short out. One bad injector can cause problems for the other three injectors on that bank.
Jim, Spot On ! You are totally correct, one fully shorted injector can fry one of the two PCM's injector drivers and bring down, the entire bank of injectors that is being controlled by that driver.
It’s rare that I watch a 55 minute video but this level of troubleshooting, knowing waveforms and having the right tools makes him a credit to his profession. This is a very cool video and explained in a form that is understandable. Bravo Zulu sir... I will keep watching.
I worked in a GMC dealership in the early nineties, worked on a ton of these tpi injection systems. Replaced a lot of injectors. One big issue these had was when ethanol fuel came out. Fue would flow over the windings to keep the injectors cool. High concentration of ethanol would strip the insulation from the copper windings shorting the injectors. Gm even had a technical service bulletin on the problem
Suggestion for Part 2, add some 80's hairband music like Whitesnake or Poison and you'll be all set!

This is one of the few I wouldn’t be able to figure out. I’ve watched a ton of your videos and try to figure out in the beginning. I wouldn’t even know where to start. It takes a real expert. You would definitely be my mechanic.
I'm amazed you had a touch screen scan tool that supported OBD1. To me, OBD1 is sitting in a broken car in the garage with my dad as he clicked the key on and off for the secret handshake, then counting the lights flashing to get the code. Fond memory I think of every time I have to fumble with a code reader (especially before I owned one)...
This is the best freakin channel on youtube that helps you learn how to make a variety of repairs along with what tools to use and how to use them!! Thank you SMA, my favorite channel.
Great trouble shooting Eric. It pays to have the right tools on hand. I appreciate you explaining so much. I know that takes valuable time from your work.
You are a great diagnostician. The number of times you rechecked to confirm the car is not starting was remarkable. And yet, that's just what diagnosis of complex systems needs.
Professor, this is like a time capsule. Excellent, excellent video.
Eric, you are one lucky guy. Mrs. O helps around the shop, books you good meals, and has a sense of humor like you! One lucky man.
These are some of the best repair videos I've ever seen. Your one smart guy. Thanks for the posts. Keep up the good work.
Your camera work and videos just keep getting better and better. I don't even want to think how many hours it takes to do a video suitable for uploading. Keep'em coming and thanks.
+Garlin Willingham Not as long as you might think.
I am a professional mechanic(8 years) but I have to say I learn a lot from you when you work on these older vehicles. Thank you. I’ve been spoiled by modern vehicles and their more modern computers giving me all the information I ask. It’s nice to see someone teach me to use noid lights in this day and age.
I always want to own this model of Corvette as a collector car. This video taught me about this model year with common engine problems to look out for. I like the diagnostic tools and your trouble shooting method and approach.
Thanks for posting!
Nice diagnostic Eric with the Multec injectors. Very common problem with the older injectors shorting. As one viewer mentioned, best to replace them all. Keep up the good work...

Sticking that badge on that valve cover tells me you also do what I do when I find loose change in a customer's car, goes into a zip-lock bag and put where the owner can find it. That also applies to anything else found in places where things get lost. You have integrity Eric.
As a technician, I really appreciate his approach, and I actually learned something useful from him. Worth subscribing if you're a young tech starting into this I think. Keep your mind and eyes open kids, you'll learn a thing or two.
I love the look of the 1980's corvettes even though a lot of people probably like the 60's and 70's ones

I think this was one of your best yet.....glad you didn't have to get towed for the test romp......
All this info and being able to sit in..sooo invaluable. This vid in particular helped me diagnose bad injectors. Ran rough once warm then awful on hot start...no power. Replaced and now runs well. Thank you for the guidance. Respect for all you do
Thanks for an informative and entertaining video Eric. You are an awesome mechanic and a person who is fun to watch while you work!
Thats really a nice tool to be able to trigger each injector individually.
you deserve Great praise for your workmanship!
Eric O, I just watched all of your videos. this is far way the best vid I've watched. I'm a mechanic myself. but I've learned tons of diagnosing methods, thanks for your teaching how to diagnose etc, keep it coming! I'll keep on watching!
Eric you have a gift So many times I’ve seen people on CZcams and shut them off immediately because they’re not going anywhere or getting there very slowly you do a wonderful job I’m 65 years old still work on cars once in a while you inspire me to keep working good job
This one is amazing! Thank you for going the extra mile!
"Whoa, we're at nine hundred and eighty-three thousand RPMs. That's really zingin'"
983040 (decimal) is 0xf0000 (hexadecimal), so just an invalid value. Pretty standard trick in software.
Usually, software people use -1 (0xfffff for 20-bit register), but I'm guessing they had reasons to keep the lower bits at 0.
3:22 nothing looks really bizarre
What do you expect? It's a Chevy!
Good job you figured out it was the injectors bad
Maybe he swapped in an old Chrysler turbine to get those RPMs!
I can appreciate professionalism and the way you explain things. Most DYI videos the guys talk down to us as though we don't know a damn thing. But you speak as though we are one of the guys. Because you have to have some knowledge to even be interested enough to even watch videos like this.
Thank you for sharing your experience and knowledge.
I really enjoyed that vid, I'm a 60 year old shade tree drag racer trying to keep up with the newer tech. You sure have the gift of teaching, was able to keep up with a bit of your coaxing. Thank you so much will watch part 2 the conclusion.
Wow, that's a mechanic ! Good job, Eric !!!
I believe I'd put him on the super technician category.
I respect you and your work. I hope to be a great tech like you
LOVE the scenery of you town. Reminds of Mayberry, Andy, Opie, and Barney when I was a kid.
Another quality interpretation of how not to throw parts at the problem, as so many inept garages do.. Keep plowing deep S.M.A.P. ..
Thank you, Eric My car had the same problem, now she runs GREAT. Bill
+bill cash Glad it helped
good job I have done 3 or 4 of them ,injectors all go to he'll on that car and the water pumps to. very well done Eric.
I am glad I dumped my Chevy TURD and got a Supra!
“Take my word for it” ……you are the only mechanic that I would !
Great in-depth technical info, as well as diagnostic approach and conclusion. Very informative. Keep up the great work. We'll done!
Great Video! Hardcore...., you have excellent command of electronic diagnostics...., two thumbs up!
Most definitely a better grasp of electronics than Scotty Kilmer and the "other" Eric(ETCG1)!
Hi Eric, you live in a lovely area you lucky thing. Love the vids. WhitwellMike
I saw part 2 first. Listening to the bushing of this one, same symptoms exactly. Thanks so much. I'll do some diagnosis myself. Love your videos!
Wow, you really know your stuff. Im an electrician and you were in our upper profession, as a mechanic. I know guys that been in my profession for decades and would be clueless. Your customers are blessed
OH MY GOD ERIC I MADE THAT TOOL! WOW GOOD OLE KAL EQUIP! Thanks
Wonder what they are worth?
Well done Eric. I'd like to see some more OBD1 work. Great video and sound.
+Dennis Wilkinson Ha all the OBDI's are in the crusher.
Really awesome seeing your analytical diagnostic skills in action.
Excellent diagnostic! Thanks for the good and bad injector graphs that is really helpful!
Man I hate when your videos end. Seriously I watched this and it felt like about 10 minutes. Keep it up brother! Love the long vids!
+Jacksonkellyfreak Don't worry there will be more haha
Can't wait brother!
Can't wait for Part II. I always learn a lot watching these vids. You must have a ton of money spent on tools. Great job. Thanks.
+raykrv6a Yeah I have spent a buck or two over time.
This is one of the best videos I’ve seen. It also hits close to home with my new project ‘87 Corvette in my garage! Just getting into the old-school OBD1 and looking for suggestions on my error for the MAF burn-off error. New relays and I can see the actual wire glowing after a shut off. Thanks for your great content!
I’ve been watching your videos for a while. You seem to be very thorough, we need more mechanics like this. New sub here, keep the quality videos rolling. Best of luck in all your endeavors!
Now I understand injectors...another fine video, my friend.
I had the exact same problem with my '96 C4 with the LT4 engine and it ended up being a bad EGR valve.
I was ecstatic that you have the same labscope I have. You showed me more features I didn't know how to access. Great video, Boss!! Thank you!!
GREAT Job Eric , Me worked at a GM Dealers for many years , its a common Problem on those's Port fuel cars.
Just a simple ohms reading will tell ya what the deal is. If you have good fuel and Pressure.
Another Problem with those's is the Intake gasket, they suck oil in from the bottom part of the gasket, and the intake valve
is blocked from carbon build up , and not letting the fuel to reach the combustion chamber, And/or the valve seals.
Your lucky living in a small town , no Traffic , for a good road test as well !!
Keep the videos coming Eric , Love your dogs as well !!
Those older-style injectors were never meant to have 10% ethanol-laden gasoline sit inside them and heat soak for prolonged periods. If you think about it- an injector is a type of electric (stepper) motor. If any (even low a voltage) electric motor is kept from moving, or a "drag" or "load" on it's rotor- it will build up heat, and (especially in the small windings of these) become weak, and eventually burn out. The gumming properties of the ethanol build up, shorten the throw of the pintle, then this weakens and burns out the coils. Also- given the hygroscopic nature of ethanol (why it's not used in aircraft) I'll bet the insides are also rusty. Eric- after replacement of these- could you please autopsy the weak units and show us- to confirm or dispel these ideas? Thank you so much!

Maybe you mean hydrophilic (water loving).

HUBBABUBBA DOOPYDOOP why is ethanol even used in cars since it causes damage and gets worse gas mileage. It takes twice the amount of alcohol than gas to run

i really appreciate you taking the time out to do this video. if you think that scope software is a mess. you don't want to use the pc version
+Rayon G I can't use the maxi-scope PC software... it doesn't work lol
I apologize if this has already been said, I don't want to search through nearly 800 comments. If you pause the video at 45:48 you can actually see the mechanical opening of the injector. That small little drop in the middle of the current ramp is actually the injector opening. You don't see that small little drop in the bad injector because the injector is unable to pull enough amps to lift the pintle off its seat in the injector. The reason you are getting too low of an ohms reading is because the injector is shorted internally. Since it is shorted the voltage is taking the path of least resistance and bypassing most of the injector coil, that is why the ohms is low. I really enjoy your videos. Keep up the great work.
Howdy Erick, I recently had same problem with my 94 Vette. I watched your video and I thought my prob might be same as yours ended to be. I purchased new injectors from corvette mods, rep,aced and didn’t fix my problem. So, I ordered new optispark and water pump , I took old parts off with no problems. My 94 is very clean .did not show signs of oil and or water on optispark, I replaced both seals as well on timing cover, installed new distributor abs water pump, I also went through harness checking possible brittle wires and connectors. Ended up running new grounds from battery to injector rail ground point and body to block. Cleaned throttle body, already replaced icm, solenoid and the easy stuff a few months ago. I’m pleased to say your video helped me learn my C4 in more ways than most. After I put er all back together with new optispark, she purrs and runs great now. I’ve had her about 14 mos. hadn’t put 100 miles on her before she started the engine stall stuff. I believe my problem may have been related to insufficient grounding and or the Optispark replacement . Havnt found a for sure fix for similar problem. Thought I would share my results. Thanks for tutorials.

Hey Eric nice diag! When you called me up to share your findings on the Vette, I was surprised that you've never run across the shorted Multec I injectors on late 80s-early 90s GM cars... "That's because they're all in the CRUSHER" hahaha priceless!
The MaxiScope looks pretty cool. Don't worry though, they will never get around to fixing the glitches...I've tries contacting overseas-based companies like Autel and OWON about their software and have gotten nowhere.

Holy cow! Thank you for bringing us along on this one. That was some Nth level diagnosing Eric! It is going to be cool seeing part II! For that engine, wouldn't typical Fuel PSI be in the 50 - 60 range? Or being multi-port injected, 30-40 psi is acceptable? Keep up the good work, and thank you again for posting this video!
+TheTexasCoder These are usually around 40.
@@SouthMainAuto Before I clicked the video I guessed fuel pump. Had the exact same thing happen on a early 92 buick lesabre. I think the lack of pressure from the fuel pump was causing the fuel to vaporize in the rails. If you could get it started, it would run like a dog until you were able to pump enough fuel through the lines to cool them down.
Very interesting diagnosis, straight to the point and thorough. I wish you were my mechanic.👍👍👍

Appreciate the way you run through your diagnostic tool and how you explain what you're doing. Broke my next seven years ago so I've been out of the loop for a long time. But basically I was just a Master Mechanic and medium heavy truck for Cemex. Anyway buddy of mine in Manassas has a collection of Corvettes so I try and pick up on all the Corvette videos I come across. Coming across your page and the way you explain not just this car but all your other cars is very helpful and educational. If you've got some mechanic who's on the border of being a competent mechanic and a master or really good mechanic your page and the way you go about Diagnostics and explaining what you're doing could really help some younger guy who's on his way up on the talent ladder.
Anyways, keep up the good work brother, please don't take it as an insult when I say it's very entertaining to watch how you go about doing things. I mean that in only the most positive way.

My 88 GTA (which sits) had this same problem....With pretty much the same identical issue....When she warms up she falls on her face... Spark is good, fuel delivery is great at first..dudes even dropped a new distributer in it...
Still nothing...
That is, until I saw this video...This boy is a rocket scientist !!
mine was a bad injector driver due to jacked injectors from sitting...
I give you a mega thumbs up with a bell !
You'll probably never read this but anyway.... Don't forget, the higher the heat the higher the resistance; and vise-versa. Higher the resistance, higher the heat. That's why you read less than 2 ohms and later you read 8. The coil was cooling down. Learned that on F-15's 30 yrs ago and Ohm's law has worked for me every time. Learned a lot watching your channel, so keep it up ol' boy!
I love it when you do the brake cleaner thing. lol
Thanks for the vid!. from the get go I thought it was a bad plug or fuel pump. I own a 1985 but runs good. I'd go ahead and replace all the injectors.

Would spraying the injectors with canned air be a good way to verify it was temperature related? Working on computers that was a good test for thermal failures.
Yeah, using "freeze spray" just like thermal sensitive electronics, because they ARE electronics!
Better just use air from the compressor.

+Gylan Underhill on it's way..
Me too good diagnosis but I think it had 2 problems it quits firing as he spins it. No fire no injected pulse that could explain the start up with brake clean. I bet it needs a pickup coil or it is burning a hole in the rotor
Nice! I have been chasing what I thought was a heat soak issue on my Malibu ski boat which has port FI for about 3 years now. All the basics have always checked good such as fuel pressure, spark, and power to the injectors. I have never thought to check resistance on the injectors when it is acting up. Love the videos!
Had an 86 Corvette about 12 yrs ago set a 34 MAF code when driving. Ran the usual tests and found nothing. Measured the resistance of the injectors and 5 were shorted. Replaced them and fixed the car. You never forget the ones that test you.
Parents gave me a 89 vette. Did the same exact thing and ended up doing a ohm test right away and it was my 3 rear injectors on the right side bank of the engine. When it wouldnt start i would unplug those 3 crank it and it would fire right up. Plug them back in and tried to start wouldn't even try to start. From what i read that body style vette it was a common issue with the injectors.
+Devon Morder I have begun to see these multec injectors are an issue.
Shitty mid-late 80's quality for you.
What's doing? Is the low resistance pulling down current for the entire bank and preventing all injectors from firing?
@@ModMINI its not pulling down the current so much as Its being diverted to the easiest path to ground but the actual current going to the banks will still be the same
