- Ford Ranger Misfire Fuel Injectors . This 1999 Ford ranger 3.0 V6 came to me with one dead cylinder misfire. Checked for spark on this ford ranger . Then checked Compression on this ford ranger 3.0 V6 . Reset the cam sensor because it was loose and able to turn on its own . Cam sensor turned , may be part of what caused the ford ranger to think it had a misfire on number 3 cylinder when it was number 2 cylinder misfiring. Put a new set of fuel injectors in the ford ranger 3.0 v6, after ohms testing the fuel injectors. Spark plugs , tightened the clamps on the air intake and it seemed to run pretty good after that . 02 sensor seemed to be ok after the fix and the loose wire only ran the temp gauge in dash.

WOW Terry with the cool tools...Very impressive. You are a good mechanic sir
Right on WTBM!! Been looking around at Rangers, crazy at the prices of them these days.
Thanks for sharing "the hunt" and your knowledge!! *Have a good'nnn*
That was a pretty big job getting that figured out. Having the right tools sure helps but your best tool is the one between your ears. Nice job.
At least everything was easy to get to and easy repair after figuring it out . Thanks for stopping by .
Your video editing abilities is a breath of fresh air!!! Good job.
I love this trouble shooting process. I'm having a similar issue and I think this video will help a lot. Thanks.
Hope you get it sorted out , Thanks for stopping in
I'm glad you know what you are doing. I got out of mechanicing just before this stuff became popular...
Gets harder and more costly to work on any of them now days . I remember when if you had a carry around tool box with you , you prob had all the tools needed , but not so any more . .
I hate computers they cause more issues than they solve, mechanics and electronics is not a good idea not when it comes to vehicles, vehicles are basic mechanics with your typical fuel to air ratio ots not like we're piloting a freaking 747 here lmao
Sometimes the 'cheapy' Harbor Freight DVOM can save the day. Got your hands full with that truck, some hack was in there making things harder for you to diagnose the issue. Nice vid, cool.
had a clue when seen the pulse widths , but wanted to show all the steps . Thank you
Did you ever solve the rough idle at the end of the video. I am having the same issue were the idle is a touch off but soon as it does above it smooths out. Has been driving me nuts for months and I have done a lot of the same stuff as you did in this video
Anthony Spadaro do you have a V6 are 4banger,I own a 96splash since new over22yrs ago.
I wish I would of been more interested in fixing cars by my dad when I was younger. It would of saved me a fortune in mechanics.
Then you would need a fortune in tools . lol
I had an old 94 ranger that started running really rough. Went through all the regular things, plugs, wires, even the injectors. Turns out that the vacuum system had gas in it. There was a vacuum controlled valve for the injectors (I think). Anyway it was allowed too much gas into the cylinders. Changed it and ran super!! It had a 4.0 eng.
Thank you for sharing , It may help someone who has the same issue .
Thank you. Thats why I wrote that in. I thought it was an unusual problem.
What was part called
I'm having the same issue. I changed everything, but my car is still running rich. What's the name of this vacuum valve?
Great Job on Diag! Good explanation! Seems like you have a solid truck there now ... I have owned 3 ford rangers! Great Light Trucks!
you have all these fancy tools, i gotta replace injectors, coils, and plugs until one of them does the trick lol
Thanks for watching and commenting
Me too lol he makes me want to buy the fancy stuff!
To test the injectors though I'm just going to use the screwdriver trick so I don't have to drop 180 bucks on new injectors just to find out that wasn't the issue 😬
I wish you wouldve shown taking off the top of the motor to get to that fuel rail. Do i need to buy a new gasket for that intake if i take it off?
Yes
Dang I wish you were my mechanic!
Finally the answer to my problem iv thrown everything at it. Couldn't figure it out. I was hoping it was an injector but. It is
Thanks for stopping by and commenting
this guy knows what he is doing! Good overall because he sees problems while he working on another problem.
Thank you
nice repair.... i had the same thing on my 97f150 v6 i also cleaned the throttle body
Thanks , seems the throttle bodies like to get dirty on a lot of them
yes when i went to check i seen they have there own cleaner for it
Yes , It will leave the coating on the throttle body , where other things may remove it . Same for MAF ,
did not know that...ty
Thanks for the good video.
Thank you for stopping by
11:22 you said you put your motor on top dead center Now is that the # 1 Cylinder at top dead center I nead a little bit more info on this
That’s a great video and thanks for sharing 👍👍
Thank you for stopping in and commenting
Wow, what a challenge.
had quite a few issues . Thanks for stopping by
Good vid!!
Thank you
Nicely done.
Thank you
Question I have a Ford ranger 99 when I first started up it runs great as soon as it starts to warm up number four cylinder starts missing I replace the spark plugs wires do you think it's the fuel injector
You would need to figure out if it loses spark or fuel . Have you looked at the coil for cracks . I may think coil first . You can also test the injectors
Isn't the code for the actual firing order of the plugs and not the cylinder number itself? I thought I read that somewhere, battling with same issue on my 97 Ranger right now. Saying misfire on Cylinder 3 which in firing order is Cylinder 2 on the truck according to my haynes manual.
interesting.
Good video !!
Thank you
I wonder if the cam sensor being out of position produced an incorrect misfire code?
It appears that someone else has been in there monkeying around prior to your investigation.
Thanks for sharing.
I believe it was . Thinking now i should of tried making a misfire after the fix to see if it was right after
Brilliant!
Thanks
My Ford Ranger 2001 V6 has misfire on cyl 3 but only I get the check engine light when driving about 60 to 70mil/hr and accelerating up the hill. Plugs, coil pack and wires are new, no fouling on plugs. I erase the code and can drive in town without light coming on. Any suggestions.I was thinking to change the fuel filter first before I start messing with injectors
fuel filter will not pick on just one cylinder
I would think if filter is clogged the lower fuel pressure would affect one or more. I actually found a problem; it were Bosh spark plugs which lost their post on the insulator. Four of them were lost and I could insert needle in the porcelain so they been firing without metal exposed @@wtbm123
2002 ford ranger misfire at 3000 rpm what's the problem
Did you have to restrict pressure or cut the fuel somehow before you removed the fuel line to injectors?
just pull the fuel pressure fuse
Pull the fuse and run engine until it dies
yes need to release the pressure , easy to pull fuse or relay and try and start to release pressure
Hi, I just bought a ranger v6 3.0. That engine is the vulcan? thanks
Días de Vinilo Uruguay yessir
A quick way to check fuel injectors is butting a long metal rod against each injector and listening with the other end tightly against your ear. You can even feel the vibration pattern through the rod with your hand. Sluggish injectors fire much slower than the good ones. If the [injector] firing rhythm isn't consistent, it's time to replace it.
And Rapp on it with an extention --some times will free it up -temp fix !!!!!!!!1 Ronster

I have a 2001 ford ranger and am trying to diagnose the problem. Im almost positive its the fuel injectors because ive replaced everything else except checking for vacuum leaks. I have 3 codes that popped up P0171, P0442, and P1131. My vehicle wont go over 35 up hills or when its cold. Could this be because of the fuel injectors?
Hard to say with out seeing the data , but also see if Maf is dirty
Any video of where to place the red and black probes on the injector to test ohms read out ?
I believe these injectors only have 2 terminals , it should not matter which lead is on either terminal.
That was a good days job . Was someone else at it before you looked at it - seems them loose clamps might indicate someone was there.
Yea thinking they tried to time it , had the air intake off and had changed spark plugs
Odds 'n evens...Don't you just love being the next guy to fix the previous guys mess...I''ve got a Nissan 4.0 v6 with a smoke issue...You ever played with one of those.?..You may want to take a look at where the water pump is.!!Nice investigationing Terry.
well done Sir.
how common is an injector failure?
coil on these is more common , but not surprising on one of these if a injector fails.
Can you do a video on how to change out the fuel injectors?
If i get another one in i will do another video .
👍👍
Why is everyone hating on this mans tools? Some of us are evolving and the rest are filling an evolutionary void. I bet you have a lot of broken shit too.
Thanks for watching and commenting
That gave you a run around lol, but the computer getting 2 and 3 mixed up was no help.
i guess that the cam sensor being loose was the reason why the computer didnt know what the hell it was doing.
And the death of an injector to add to that!!.
That meter is cheap but accurate enough.
You were doing a comparison only, the meter could have shown pictures of fruit and as long as all the injectors showed "Banana", they are ok lol :-D.
The bad one would show "Lemon" of cause :-D.
So as problems come in three's, you have to fix the running mixture problems.
You are a patient man :-).
Where do i get one of those meters with the bananas and lemons . My OTC meter is un reliable any more
i think you can purchase on at the local arcade, just look for older fruit machines and ask the repair tech :-D :-D
my 2000 ranger sometimes dies when i put it in reverse wheter is cold or I've been driving for awhile and the idle drops hard sometimes,
i i found the fuel injectors for $40 each at Amazon and they are the motorcraft
but im not sure if it maybe the MAF that is not letting the air thru
its a flex engine with 15000 miles on it
your video gave me some ideas ...fingers crossed
May also check the idle control valve , and look to see if throttle butterfly is clean and not dirty
I have a Ford Explorer 4.0 SOHC it runs great except for a rough idle it’s not crazy but I’m thinking it could be a misfire I’ve checked all vacuume lines and nothing I can find but I would think if it was a misfire I would lose power but it doesn’t feel like it if anyone could help or had the same problem I need some help with this thanks
May check , or try cleaning the MAF , IAC and throttle plate.
Mine is doing the same thing if anybody can help me mine is a 96 with a 6 cylinder I am far from my Motorhead but I know I am getting fuel to the fuel rail and if I FI steadily poor gas into the throttle body it will continuously run as soon as I stop it guys like it is not getting fuel I don't know if there is a fuse for the injectors or a relay for the injectors but I am Unaware of but apparently this is a common problem someone please help
I had the same problem, it drove me crazy and at the end it turned out to be a plug.
I had the same problem with the plug on cylinder 3. It was seized up bad and a pain to get out. Big thanks to PB Blaster penetrating oil. I was losing my patience and almost broke a swivel wrenching on it like an idiot. I'm lucky i didnt break the threads. Always check the cheap fix first. Your comment was my guiding light.. Thanks buddy
You had your work cut out for you on that one. Nice work.
It was in need of maintenance. Thanks for stopping by
@@wtbm123 What did you end up doing to fix it
Ford... nuff said Lol. Hey Terry.
LOL good truck .
You mention the full injections as the source of the problem. But that cam synchronizer being so loose seems like it would have been a much bigger issue, being like 20 degrees advanced on the timing. I have a 2001 3.0, trying to diagnose an intermittent twitch/stumble at idle, about every two seconds.
Yes cam sensor was part of issue , but it does not single out one cylinder and this had a dead miss on one cylinder . . have you checked to see if throttle plate is dirty or dirty iac valve
@@wtbm123 throttle plate - yes. IAC - no, good idea , i'll try it tomorrow. I did find yesterday that my evap line to the throttle body had a 4 inch rotted crack along the length of the underside. fixed that but it didnt solve the idle twitch.
@@rowboat0317 Let me know if you ever got your ranger to idle correctly. I have been trying to get rid of my idle stumble for 1.5 years and spent a crap ton of money from the parts cannon.
@@BlitzHack nope. still stumbling. per the ranger forums, it seems to be a very common issue with most resigned to live with the issue. One commenter stated: "It will always sorta kinda have the infamous 3.0 Vulcan rough idle. It's normal. Bugs the heck outta most newer 3.0 Vulcan owners." I'll post back here if I ever find a solution.
@@rowboat0317 Bugs the crap out of me too. I have mine down to very minimal and does it worse on warm days or engine warmed up. When stone cold runs almost perfect but does not last long. Before you swap out next part let me know and I will tell you if I already tried it. I do wonder if my can synchro is out just 1 tooth or something very small. I had Ford replace it when I first bought the truck because of squeaking. supposedly it tells the injectors when to open.
we overhaul our pickup ford 4cylinder 2.5 1996 but wont start cranks but no starts
need to see if spark or fuel . is crank sensor good and hooked up . a wire not hooked up ,loose , missing ground someplace
you have 4 choices not 3 with that injector tester the 4th is continuous and after you make your choice you must momentary disconnect power to choose another just too let you know.
My 94 ranger is having a misfire problem, im not a car guy, but can't afford to pay for it to be fixed. Any advice ?
First check the coil and if coil is bad replace it and also replace the spark plugs .
@@wtbm123 Good idea, I checked the codes and had mass air flow sensor codes so I replaced that. (Didn't work) but I've yet to check the coil, how do you test the coil?
@@wtbm123 I have a horrible misfire been dealing with it for years. I’ve changed coil pack (3times) / wires / plugs / both o2 sensors and fuel filter running worse now than ever. Please help me sir !! I’m gonna try to look at the injectors tomorrow. The MAF is clean but not sure if it’s bad or not. Hope to hear back 🙏
Those diagnostics tools aren't that much money Great investment
Except the snap on scanner lol
Not to pricey to get a basic scanner , and they come in handy
True
Wish i knew about cars a guys selling a Ford ranger XLT 2008 automatic for $1400 bucks and its super clean no rust.
I dont know the Blue book but its super clean but on the description it says it has a Miss fire.
So im not sure what it is or the cost. My girls step dad is a pro and fixing stuff but not sure how much it would cost i really want the truck.
Hard to say , but could be something simple like a coil , or worse low compression , that one would not be good
I've got a 94 2.3L and I have a misfire bogging down issue. Hoping it's not a bad cylinder and maybe a bad plug lmao wishful thinking. Not sure of it is a cylinder because it only does the bogging down or out during the winter months.
May also try cleaning the MAF . . But nothing like hooking up a scanner to see live data
@@wtbm123 that could be as u have tape holding together parts that aren't held together by clamps and inhave noticed when I mess around with that stuff it acts up more. I don't have a OBDII plug on my 94 my model has the ODB 1 but I will definitely look into it. Great truck other than this it's a tank
I have the same issue on a 4.0 Sohc V6
They should test about the same
Having a mechanic's stethoscope and your ears would help you find that bad injector way faster. Good video though.
Yes that can help if injector is not working , but some injectors still work , just not well . but listening is a good first check . It is nice to test with ohms meter or some equipment , so one can have numbers to show costumer .
how can you tell if you have bad fuel injectors
ohms test or injector balance test
Sorry I was wrong it's the weirdest fireing order and cylinder set up all the piston have odd and even numbers together sorry I was wrong
I agree it does not seem normal . But i am happy to have you commenting , i had to look again to see , as i am not above making mistakes . With trying to hurry on peoples cars and filming i have said things wrong before . Thank you for Commenting and watching .
Nice trouble shooting and repair.
Thank you
mine my does the same thing mine is a 93 with the 4.o motor
Great Video ! I need Info. Help . with my 2000 4.0 L ranger getting a P-0171 Lean code BANK ONE .. it running great but after reset the P C 420 miles I get a rough Idle for a sec. and it Pops the check engine lite .. it is getting great gas mileage . running well could this be a bad injector too thanks Man No one can fine the Prob can you help thanks oH it had a new cam Position senor at 72 ,000 , Now its got 215,000 thanks
4.0 my first thought , vacuum leak . Check PVC hose . The one elbow likes to go bad a lot . . This is where a scanner with live data rules . You could lok at fuel trims . If one bank is way off , but fuel trims on other bank are good that can eliminate a lot of things . But with out live data it is harder . The MAF or Fuel pressure , CAM position sensor those things should cause the same issue on both banks . But bank 2 may be almost the same , but just not enough to set a code . But i would start by looking for vacuum leaks , That is from MAF in to engine . .
wtbm123 thanks thanks. Check for vacuum leaks seems ok. I disconnect the idle air valve and the engine Will not idle I was told by ford that show no vacuum leaks is this true. ? I have got a bank two Lean condition weeks ago. Thanks again.
wtbm123 and I have run lots of injection Cleaner thru in the last 6months I can not read the fuel trims. One mechanic said the fuel pump is good. That cost me 100 bucks just for that thanks
@@marklaciura3177 If both banks are lean , then , check fuel pressure , MAF may clean it . . To really know , would need to see the live data to see just what is going on
Ok I see the shrader Valve to check thanks look for more vac Leaks and reclean the Mass air .. Ok you told me a lot thanks Much .. the car has 135,000 on the fuel filter should just change that ? could it cause low fuel Pressure or issues .. and I will not bother you again .. I know I am asking a lot thanks very Much you told more than anyone .. the local car people Just want $ .. one told me it could be 100 things and may cost 500 bucks in trouble shooting alone .. I can't do that ! thanks again!! the Good thing the truck runs well ..I feel blessed
which motor is that?

Thank you
Wah. 6 injectors are not cheap
Thanks for watching and commenting
i know you had to replace the injector anyway but maybe try the injector cleaning next time?
I do have a video on cleaning some injectors , But this injector failed the OHMS test so it has internal wire damage . But yea if an injector passes the electrical test then it is worth trying to clean it
@@wtbm123 didnt see the damaged wiring sorry yeah you know what you are doing :) good job man
It is a number 3 and not 2 your on bank 1 .3.5. the odd number bank
just looked again and left says 123.
I wouldn't trust that meter.
Worked fine for me each time I used it ... I also have a snapon and they gave the same reading
Do not need exact number , but just comparing
Your engine shouldn’t shake like that
Thanks for watching and commenting
You are testing wrong on that side of engine is 1. 3. 5 so you are wrong scan tool right it is number 3 the other side of engine is 2.4.6 know your bank odd or even
not what my computer or manual says . right side is 123 left side is 456 . VIN U .
@@wtbm123 you are standing outside of the vehicle driver side is always the left side passenger side is the right side
Bank 1 is 135 and bank 2 is 2.4.6
@@johnrogers7682 Yes right side is always passenger side , and it shows 123 on the RIGHT SIDE .

Quit smoking or drop some weight buddy
@Fast Car Its a rouge algorithm troll response.
2002 ford ranger misfire at 3000 rpm what's the problem
Injectors can stop at certain rpm...
Would need to do some testing , many things could do that , low fuel pressure , MAF, cam , crank sensor , many things
