CAT C15 Injector Wiring Harness, Turns Out It's a BIG Job!

- Hello guys! So I'm still trying to track down some shakes that I've been getting with the truck. I know there are multiple problem areas that need to be addressed, but today we're concentrating on the "idle shake" or little "miss" I get at certain RPM's.
The internal wiring harness, or injector wiring harness, is prone to damage over the years, as it lives in hot oil, and eventually the oil will make it's way into the wire and wick itself up and out to the connector on the outside of the engine. If left unchecked it can even wick it's way into the ECM! But this harness can be the cause of a bunch of little shakes or rough idle symptoms and really the only way I've found to deal with it is to fire the parts cannon and hope a new harness helps! Hahaha.

Where would we be without our mum's, they give birth to us, fed us, nurture us and help us work on our trucks 😂👋👋👋
It's cool seeing the motor run without the valve covers,your brave to work on your own truck!
Until you try it on an OHC engine... After doing my first timing belt job on a Toyota 4A-FE, I decided to test-fire the engine before putting everything else back together. I figured it would be OK with no valve cover, like the OHV engines I'd messed with, but no. It sprayed oil EVERYWEHRE before I got it shut off...😫 Now I set the valve cover on the head with a heavy weight on it, when I do a test-fire before putting the rest of it back together.
Your not only good driver, you are also a good mechanic. Love your videos. 👍 👍 👍 👍
Very impressive. I get nervous opening up my motorcycle to change the shims. If I screw up, I don't get to go play in the woods. You're working on your livelihood.
You have a lot of courage - and trust in yourself and your ability to learn and resolve issues. Very impressive- and so calm under pressure. Nice to see you being rewarded. A great channel- inspiring video.
Nice to see a young guy doing his own work like an old guy did back in the day. Sometimes you just have to suck it up and do it. Great job bro.
I miss the old trucks. But trying to keep an old one on the road just got tiring to me. Every trip out was something new to fix. With the newer truck I can go a couple months sometimes with just tightening up a bolt here and there. However being down a week due to an emission sensor really sucks.
You're a BRAVE man, Matt! No way would I have attempted that on my own! And outside, too.
The packout setup is sick driver. Brilliant idea
Im loving the issues videos, really shows the ugly of trucking, makes everything more enjoyable when you fix, upgrade and try different things
Your courage is something man... U dont know what those plugs or pipes do and yet u r working on it... Damn..🔥
absolutely love this style of vid
This is what I was waiting for! Startling!
OLD TRUCK I have been driving 1985 359 for 28 years KEEP ON TRUCKING BROTHER ✌
Great video and great job! Your parents’ place is nice. The bird life there sounds awesome and was a nice soundtrack to your video.
Enjoyed the sense of humor Matt , you need one when working on the moneypit , albeit a lovely looking moneypit .😁 nice looking tool kit by the way . It looked a bit daunting but you did a great job , the shake ometer 5000 looks a handy piece of kit to have 😁 . I must say she sounds great running as always .
a very good job man!! I really like your videos!! 👍🏻💯
Nothing like a guy who knows how to fix his own truck, I’m sure you saved thousands on this job by doing it yourself. Today lots of guys don’t even know what fuel injectors are let alone work on their own trucks 😂😂 Props to you bro, you got guts.
The oil can walk through the wire due to capillar effect. In bad case it can walk till the EPU. In germany you can order plugs between the connector and the sensor. It stops the oil from coming into the wires. Sry for my bad english.
13:33 I need so badly such huge "momentum arm", for my seized, dumb, stupid, bloody, stucked oil pan nut 🤣. Just exactly right now!!
Good job Matt!! Keep it up bro 💪😎
Got to admire your braveness (especially you not being a trained mechanic) but as someone else commented .. always cover induction tubes ... and a smear of silicon on multiplug 'seal to casting' would prevent leakage .... You could do with a heavy vehicle mechanic as a friend ! ! ! .... respect to you from England.
Excellent job dude I really love your videos they are very interesting at least you can work on your own truck very nice be safe out there here from Ontario Canada 🇨🇦🇨🇦🇨🇦🇨🇦❤️❤️❤️😎🚛
Got the skills to pay the bills!
Seems like she has some prettt good power!!
Good job dude! Ya know its bad luck not to have a name for your truck. I named my 97 F 150 " Old Mr. Ford"! I just recently named my 2018 Cadillac CTS "Mrs. Finally Paid For"! Be cool--be safe!
Haha she has a name but you gotta wait buddy!!!!
Great video buddy
Great video!!
You got cannon balls to take that project on my man! I earn money to pay people with a higher mechanical IQ than mine to do jobs like that.
Mechanical IQ. Now I know what I'm missing. Haha.
You did a great job bro. I deleted a previous post thinking you were still a accert motor..my bad the single turbo in my face….my bad. But this is another theory. Its a long shot but the Iva’s are disabled from your tune..There clearaces from the intake rocker are 20 thousand give or take.We know they are disabled…They are hydraulic acctuated pistons like the jakes.They have springs on the actuator pistons to make them retract once the ecm commands. Its a far fetch but maybe one of those dead iva pistons is bumping a intake rocker arm giving you fits
Yeah it is technically still an acert engine, and I had that EXACT shake when my engine was first tuned. The IVA’s weren’t backed off internally, so on a good pull up a hill, the oil pressure would build up enough on its own to actually actuate the intake valves and it gave me a shake. Not gonna lie it felt like that shake came back but the Iva’s are triple checked to be backed off so it’s not that ☹️
with the cold start issue it might possibly be injector cups. I would assume they are original to the truck. just food for thought keep up the good work and keeper greasy side down Matt!
I sent it in in January and they found 4 injector cups leaking, so changed all those and 6 new injectors, and I’m still having issues……
@@callthemall Im not wondering if it possibly be a timing issue if it runs okay ish after getting some heat in it. Hope you getter figured out
Thank you!
Just got to the sticking point on mine. Came to CZcams to see if I really needed to remove a Jake rail to get the damn thing out. Skipped straight to the exact point I needed in your video. Thank you for limiting my swearing today. Guess I'll remove that rail now. 😂😂
Exactly why I wanted to document this process! Glad it was helpful!
Only way to keep money in your pocket is to fix it yourself. I have a 17 389 I love tinkering on . Keep up the good videos
my heart sank when the rain started...
I learned that same wire separator trick from david on roadkill!
Saludos desde República Dominicana 🇩🇴
Dude, is that Spicoli's Dad's tool set? 🔧 Most excellent Matt 🤙
Hahaha had to look that up, now it’s on my list of movies to watch!
That’s a huge job
Hope this is not too late. But I had the same issue on a 2003 with the low airleaf suspension. Turns out I accidentally replaced a suspension airspring with one from a non low airleaf suspension and therefore my rear-end height was always out "height specs" . Replaced both rear airsprings with factory bags and problem solve. Good luck
I still love working on my truck it’s the only way to go and it gets done properly nearly every time I use a mechanic I regret it. Outside awesome listen to the birds cheeping nice a quiet.saving a small fortune tax free. And really getting up close and personal with your truck. You just can’t put a price on how good that is.well done ✅👍😊👌
I don't mean to be critical, but I was so afraid of you hitting one of your bolt/nut holders and knocking them off and nuts and bolts going everywhere. You might put them on the table to be safe when you aren't putting them on or taking them off. Also, please put a cover over the air intake for the turbo. Imagine this; Oh darn, I'm missing a nut, where the heck is it? Can't find it anywhere. Get another one and move on. Start truck and hear rattling in turbo. Uh oh!! I learned these over the years the hard way, hopefully you don't. Nice job, your patience is great, maybe you threw wrenches off camera? :-) My jobs aren't usually complete without racy language and wrench throwing. LOL!! Did you ever think of using a drone with camera system to assist in backing trains? I know you can get them that will lock to your location and follow you.
Nice bro ✌️
Sir, I asked you a question, during a previous vid of yours, had from a Riding Shotgun video, and realize you probly have no idea what I'm asking about. Sorry. Semi seriously; do ya learn how to be a mech of these semis at Truck Driving school too? 😂 Hahaha your brave openin that engine up. How coragious. I love hearing the happy birds in the yard too. Awe, shoot rain. Love ya laugh. Peace 😊
Hey I must have missed your comment! No they definitely don’t teach you this in Trucking school 😂
Bonjour
Superbe présentation sur réparation de injection
Je suis un chauffeur routier français je me suis abonné 👍👍👍🤣🤣🤣
Your a funny fella. Hello, Burglar! Knock Knock, must be having a shower. HI Mummy, that's funny and good value. Your a good fella, a Good son.
I have an 06 acert and had the cold start issue and it was the coolant diverter valve.. either the harness or needs rebuilt/replaced....
Also the jumping I had was my throttle sensor under my peddle but yes could be rear-end.
Also replace all fuel lines. Be sure your not getting air in fuel system, ive seen them get fuel from the hand pu.p primer on the secondary fuel filter housing.
Hard start can also be your check valve on the secondary fuel filter housing... its just screwed on in sode... its what keeps fuel in ur filters to start. Last would be your cam and crank sensors... they dont alwyas throw codes when they are bad and cause that bucking.
And update on the situation would be appreciated, good luck
That was a stressful watch 😱
Yikes. That’s an “inside” job, as close to a clean environment as possible but you GOT TO DO..what you GOT to do!
Hell yeah!!!
Man, you guys really got a put what year it is
3400 series engine are cam in block aka push rod engines and...
C15s are cam in head engine aka rockers actuated
Is that correct?
The gray smoke when cold is just a bad spray pattern from the injectors getting old when its cold , my 2003 MBN with 1.5 mill 45000 hours did the same , but it ran fine try change the check valves on the fuel filter housing they are 3 , ones a bleed screw and it's solid and 2 have ball valves in
My c15 just died and spun a bearing at 1.5 million
I ended up getting a MBN ACRERT, with a single turbo conversion 17000 hours on the engine
It had the IVAs deleted on the ECM.
It just been installed in my FLD 132 and I'm ironing out some bugs
Read your cat manual your mom is awesome make sure you give her a big pat on the back for helping you . Very cool.😊
You just have to remove the steel lines at the front of the head and the rocker cover comes off .it will squeeze past them if your mean with it , but risk braking a tab off the cover
I have something similar going on with my 05 379 C15 Acert. I’m wondering if it’s something in the power converter?
Yeah best thing to check is for metallic bits in the oil, and any play/movement in the driveshaft
You’ve got a lot of courage Matt. I guess it’s hard to get perfection from the old girl… or is it an old boy ? Can you tell us that ?.. at least
I think it’s an old boy, cause you said it’s the name of an old cartoon superhero. And I don’t think you want to ride in Woderwoman.
Hmmm or maybe you do 😜. just foolin around he he .
Haha ol girl, and not necessarily a super hero but a 90’s cartoon character 😉
Must be the Woodstock Ontario on route
That shake could be coming from a trailer tire. Ours does it at certain speeds. The vibration at an idle point I’m fighting myself.
Shake o meter 5000. I might steal that one! Lol but i have vibrations thur the truck at idle and driving. I have a frail wire on the injector second one up front. Could that be mines too?
Could be!
So I’ve been watching a few of your videos. Do you think you made a mistake buying this particular truck ? Considering all the problems you’ve had?
I was impressed with your shifting video.
You have your own authority! Does this mean you have your own customers? Or do you use a broker?
And doing the mechanical repairs on your own , is that affecting your loads , or is it really saving you money.
Kudos to getting into this with great aspirations
I don’t think it was a mistake. It’s an old truck so it’s going to take a lot in maintenance, but there’s no after treatment issues to worry about which is the biggest thing. I have a mix of customers and brokers with my own authority. And doing the maintenance on my own does save me money, the downtime is probably about the same vs bringing it to a shop. Cheers! 🤙
@@callthemall Good for you. I got a suggestion on tarping. I got stretch rope and laced in in all the D-Rings on the sides. I also tied the rope on D-Ring end flaps. Tie on top ring bring down enough to reach trailer and tie back up to next ring and so on Leave in place Worked great for Me AND fast.
Keep it up Mister
Did your new injector harness come with the round plastic retention pieces the nuts go into that go over the 2 studs on the injector. Mine came off in 2 halves and my Cat dealer cant find anything on them
Nope it just had the circular metal contact plate that the injectors run through unfortunately. Surprised a cat dealer can’t get them 😳
@@callthemall i ended up finding them. Had to do the counter guys job for him
Ask KT3406E. That guy will know what that oil quill thing is
Boy does that dude know his diesel engines, especially Cat’s!
7:10 yikes I thought those 2 little bolts were gonna fall in.
I gotta check my injectors on C15 acert, getting diesel in oil, any other ideas what to check for?
Diesel in oil would be the injector o-rings I believe. I think maybe Fuel pump possibly but I don’t really know for sure
@@callthemall it was fuel pump, now I got weak number 4 injector, it could be the harness or injector
Rtv young man Wac em with rtv a bit
❤
I would have grabbed some Puppers and helped you
How much was wire harness and how long do you think it took
They are about 400$ Canadian for each of the 2 harnesses under valve . It takes a couple hours
Hey you ever find out the problem? I’m going through the exact same problem on mine
Bad injector(s)
see how your external wires look swollen? the connector is sealed so well that when oil starts pushing into the connector it can push right on up thru and into the wire on the other side. that changes the impedance of the wire and messes with your injectors.
Good catch! I have the external harness, still trying to find time to do it 😅
Injectors or harness. Everytime it's happened to us its been one or the other. At this many miles it's hard to get them back to the smoothness of a new truck without buying literally a new truck in parts or literally the truck
Yeppers, injectors changed in January, still having issues so let’s try the harness next!
@@callthemall how did you know the harness could be bad?
@@wilE6764 sorry just saw this and don't want to answer for the man but to give you an idea....Im a young man but the man I learned everything from my grandfather (who taught him self and owned a 50 truck fleet) taught me that when you have a shake and no major drive line components are bad it's a wire...especially when a truck gets that old. So rather then waste time chasing one wire you replace the harness because before long another wire and another wire and of course another wire will go. So you spend the 1800 or whatever it is now and get rid of the shake and keep trucking.
Should have gotten a Sony, we dont have those problems. Now those zip ties will cut into the wire shielding instead.
😂 might be next!
34:03 lol
Check your bearings on output shaft of transmission..
They’re new, plus balanced drive shaft. I actually just had the spring bushings done though and it took away a wobble I was feeling while bobtailing, tomorrow will be the test if it took away the other shakes!
@@callthemall sounds like your digging in pretty good.
Always a pest when something like this crops up.
Have you done a speed test, where you jack up and support trucks rear end off the ground.
Start and run truck.
Allowing rear end to turn, checking for odd wobble in tires and out of rotation, wobble parts...bearing seals and hubs...or broken studs..hubs are known to wear bosses out on outside of hubs..
Creating same results also.
Just watched to hubs get replaced and bearing seals, because those bosses wore out on hubs.plus one stud was broken.
Around the inner part of rear hubs, are little square tabs where the rim seats to..They wear out causing hub to be out of round..barely visable to the eye..
Unless your doing, what they call lift speed test..3 hubs replaced and axle seals
This eliminating all vibrations.
I would just get a whole new harness if you could
Yep have a new external harness that I’ll change at some point too
@@callthemall right on!
Good job , When your engine is cold what you're talking about , All of them are gonna do it , Just let it warm up on its own , That's a cold start poppin missing everything you're talking about, in your kind of weather pull up a cold START page for truck diesel engines And then you will understand what I'm talking about , The shaking you're talking about , you're correct one of the injectors , But whatever you do just do not replace ONE, replace all 6 if you do not a month later another one's gonna go , you're just gonna keep getting into the engine until you replace all of them , To get the oil and fingerprints off your engine Go buy yourself a couple cans of oven cleaner , Spray all over your engine spray it on everything let it set for about 30 minutes and take a water hose to it Works pretty good ,
She sounds pretty good MATT
Thanks bud, yeah I just started getting this smoking and sputtering when I get on the power a couple months ago, so it’s a new issue where something has changed and is not quite working properly. Could be a sensor issue but everything is reading right on the computer, could be head gasket starting to go even. I sent it to the shop a month or so ago and they found 4 injector cups leaking so changed those and put in 6 new injectors, and I’m still having the same issues…
🖐️👏👍🥰
Hi
whoops ... 🤣
Those will break down overtime, zip ties, get brittle or break apart and you will have pieces in your engine
Willing to bet that the vibration issue is a bad harmonic balancer
That’s on my list of things to load up into the parts cannon!
What's up
MATT STARTING UP HIS DIRT BIKE
Hey buddy did you find your miss??? I got vital info cat has a factory defect in these heads its the injector seats you can remachine them on the truck..the tool# C153055 or C15-3055 it's a two piece set after you do this unless seats are beyond repair...you won't have that miss..try to look up cat 3406e/c15 injector seat repair to learn more...the miss is a common issue stop wasting money I've done all this once seats re.achined injectors seal in seat on head the bottom o ring sits even now.cat will not tell you this or admit it of course they want us buy parts. When injector dosnt seat we get air in fuel...wish I was back in Ontario I could fix that for ya
No more combustion( air in fuel) ill check back on ya
Interesting because I’m about to change the injector cups for the second time in two years!
Dont ever sell that truck for one of these new POS
i was so nervous seeing all those bolts sitting on top of the coolant reservoir
Cool video thanks…I will say you ain’t scared of nuthin’ ….great repair job
