Man, I should have learnt mechanics when I had the chance! My father (retired now) used to be a mechanic... a really good one I might add. Was one of the chief mechanics for Ford in the UK. I spent many hours talking to him while he worked but never tried to learn anything... what a waste. Thanks for the video, brother!))
I've always had an interest in mechanics and how things work. We each have our own talents and interests to be sure. Yes, I would love to meet you as well. Maybe one day.
we do indeed have our talents and yours I find very interesting)) yes, hopefully one day, my friend))
my method is much more crude than yours I just start swapping out parts until the damn thing runs I think your method is much better!!
And that's okay when it's your own vehicle. That's what 98% of the mechanics do to and that's not right. I've been overcharged in the past for work and I'm hoping that won't happen now. But I know my limits too. Thanks for watching Pops.
If they can do it so can we. Knowledge is a good thing and it's nice we have channels out there teaching us the right way. Good diognostics buddy I look forward to more. 👍👍
Thanks Steve. It's been nice getting to know you.
It's a double edge sword when you have to invest in diagnostic kit to work on these modern trucks but it's good when that kit points to what's gone wrong !
Glad it worked out and I enjoyed the two vids !
Thank you for watching. This one was fun for me but i'd rather learn on other peoples broken cars. :)
Hey nice fix Wyatt. The sound of the engine firing up is always fun! Take care - Glen
Boy you got that right. :)
Great job. I still can't figure mine out. Checked crank sensor. Replaced module and coil. Now it sounds like it sorta wants to turn over. But still no start.
Quick question did you ever find what was wrong with it because I replaced the module and coil as well and am trying to figure out what it’s still won’t start
Very nice step by step Wyatt and the best part is turn the key and it started right up.Good job.
Thanks Jim. That was the first time I used my Vantage and I for got to look at some square waves. I'm doing that so I can learn the tool.
Thats the best way to see how it works hands on
That was terrific Wyatt ! Very happy to see you in action , and even more happy with that happy face result. Terry is right about the bug ya know. Soon you'll be hopping on the Staten Island Express as Ivan calls it. Looking forward to the next video already. Remember nothing wrong with doing a video showing things that are working properly either . So to follow up Erics question about that white wire , perhaps do a short video on what one should see when all is good. If you don't know what good looks like you can never be sure what's really bad. Plus it's good to start your own little library of signals while all is working. That way if the truck goes down let's say for a cam sensor and the new part isn't up to snuff you'll have a reference to use with that nifty little vantage of yours.
Outstanding idea because as I'm learning it would be good to reference what things are suppose to look like. I'm still learning this Vantage but I'm already on the hunt for something more capable. I know you love that PICO. Ivan has been showing that lately too. It's at a price point that is almost attainable for a DIY'er like me. Thanks for the input and support.
Excellent job Wyatt! Thanks for showing step by Step..
You never know who might be up against the same issue looking for answers. Thanks for taking some time to watch and comment.
Great repair and no lights. Awesome job!
Thank you very much. It was fun seeing that test light blink!
Of all the mechanical videos Ive watched none of them showed anything about disconnecting the battery w/ the key on. sorry you had to go through this. At 69 I still love learning auto diagnostics.
Very nice fix Wyatt, and now that you've got the bug, you'll find that you'll start to enjoy diagnostics when things start to break :)
I was sure happy to see that test light blink like it should. I don't know what I would have done if that didn't work. But your right, this can get addictive.
SUCCESS! Great videos. My repairs usually don't go as easy but I get there. LOL! Well done bud.
Oh there was plenty of cussing going on. That's the art of editing. I made it look simple!
I here you. I cuss as well. never been great at repairs. Just stumble through. LOL! Enjoy the week.
EXCELLENT!!! Well done Wyatt.
Thank you buddy.
Very nice fix Wyatt. Major bonus points for showing the waveform on the Vantage!
Me looking at a wave form is a like a hog looking at a watch, but someday I'll look at one and know what the heck it's telling me!
Haha, yeah. I know what the waveforms mean but I'm still struggling to get them to look all pretty like they do in the service manual. I verified the function of an oil control valve on my Mazda yesterday but for the life of me couldn't get the waveform to look right. The Vantage didnt' have a guided test for this one so I was on my own with the scope. Still too much of a rookie with the scope I guess. Oh well, practice practice!
You know what? At least we take an interest right? Hey, thanks for subbing the channel. I'm one of your subs too.
That's right. Thanks Wyatt!
+Baxrok2 Ha me too now , so let's get those videos rolling eh!
Great job! The added smoke screen added to the fix
Hey man, thanks for all the comments and support along the way!
Cool, glad ya gotten it going. Great job. Stay safe
Thanks Cary. It was an interesting process.
Nice job D, you just saved yourself thousands at some shop.
I'm into this because I got shafted for $800 for a computer that didn't fix the problem. Never again. Thanks for the support John.
I had the same issue but I replaced the module as well but my crankshaft sensor connecter sparks
Nice work, I could not tell it was the first time you diagnosed an engine problem. Very impressive! ...o='o
Hey man, thanks for the comment. I've worked on my own cars ever since I've had them but yes, this is a first for me using the Vantage and looking at voltages for a fix. I went to your channel and saw the cool picture of the Triumph. Very cool.
Good to see the proud look on your face sir :) It may have been me miss speaking or not being to clear but the wire I was thinking of was the white wire in the ICM. It should be in pin "B" IC Control Signal. I was curious to what that wire had KOEC and if nothing what it had KOEC with it unplugged from the ICM. Oh well if it dies again we can test it then! Fact is you did a test not a guess :)
--Eric O.
That's right, I went to the coil didn't I. I missed an opportunity on that one. Well, I hope there isn't a next time, but if there is I will dig in and use the opportunity to learn from the masters! Appreciate the support Eric.
Lol no master... just a mechanic !
(ha ha) It depends on the angel of the view brother. I'm a pilot but not a master. We keep learning don't we.
Dude you fly planes!?
You didn't know that? Yeah, I've been a pilot for 33 years now. But auto repair was my first love. :)
Its always good when you have a win.
It was fun!
Excellent job Wyatt! I really need a good scope for my videos!
I found this one on eBay for $160. It's only a 2.0 soft ware but the graphing meter works on anything, It ahs some nice options I'm still learning about.
That's a great deal! I need to do some surfing to see what I can find ;)
I changed out the module and it started came back a few hours later and it wouldn’t start😑 any suggestions show I change out the ignition coil also
I'm sorry I don't have any idea. This was shot over 7 years ago and I have since sold the truck.
Good job on fixing that Wyatt ;-))
When you tested that after the fix and I saw that cloud come out and I thought "I hope there's nothing there to ignite that" ;-)) That could have gotten really ugly....really quick :-P
I forgot that I plugged in the fuel control relay. She was trying to run before I was ready!
Great fix buddy 👍🏻👍🏻 Cheers 🍺🍺
I appreciate it!
Thank you leaving a comment and I hope you can figure it out.
Sweet! Nice job, Bro.
Thank you. It's my new hobby, can you tell? I break stuff just so I can fix it. :)
great troubleshooting!!! it a great feeling isn't it Wyatt :) im hoping one day to make your list hehe ICM control would have also been a good test on this one
guess i should have read the comments first :) you already know this lol great guys out there
well you maybe a 98%'er but you are not TH-cam's favorite 98%'er! haha! great diagnosis and fix Wyatt!
Your are correct my friend. You are the favorite 98%. My favorite anyway. :)
I have same truck as you with 5.0. it has a 1351, fuel, spark. timing marks line up. 170lb compression. First thing I did was install a new module. didn't start. it dosnt hold fuel pressure after the key is turned off so I put new injectors in it. it now cranks faster. [I think the injectors were stuck open and causing it to hydrolock] It now acts like it wants to start and even fires but can't quite make it. I'm thinking computer. otherwise I'm stumped. need a direction to go.
To much money to buy another one.
Since installing new injectors does your fuel pressure hold after the pumps primes the system with key on?
no. As a mater of fact it is doing exactly the same
as before. it cranks like it is out of time. I've triple checked the timing marks it's right.
I'm thinking the computer is bad throwing the firing and injector pulse off.
I'm not thinking fuel pump cause it's new and it builds 60psi while cranking.
I did clear the code 1351 and it never returned
Paul M Mine built pressure but it drained off quickly because the check valve in the fuel pump assembly was bad. may not be the same as your issue however.
wyattoneable
Did you have the 1351 code also?
SWEET VICTORY!!
Man when I saw that test light blink I knew we had her done! Make a video of your next repair bro. I'll watch it!
Missed part one, going back, got to know what that remote start thing is!!
Oh yeah friend, can't miss anything around here or you'll miss something. lol The remote starter is actually old school. I've had this one since 1982. $3.95 from Sears!
Glad it's running
It was only down for three days but we sure did miss that thing.
Success, nice job..
Boy when that test light started blinking I was on top of the world. My wife asked me "Who showed you that". I said "I did". That made it all worth while.
Awesome Brother
Thanks man.
I was wondering why there was no test for the pick up coil in the distributor
Next, airframe mechanic, you can start tuning jets. ;-) I've got a code reader/reset on my phone, (Uscan with a blutooth connection to the OBDII port) it came in handy a few times for the easy stuff, but doesn't go that far in depth. Life is a lot easier with a few extra tools in the box.....
I was a helicopter mechanic in the Army. I enjoyed that. I've always had an interest in repair and DIY stuff. And your right, having the correct tools sure goes a long way.

Well, that explains the methodical approach to diagnostics. Can't jump around while working on a blackhawk. ;-)
I have the sam issues intermittently. And have performed these same test, but I have alot of heat on my fuel relay. When this happe s ,the pump will not run. I have to cycle the switch a few times. Any help with this?
Also ,ts a 97 gmc 1500. And the pump has been replaced as well. It is intermittent though.
@@scottslaughter881 Hi Scott. I wish I had the easy fix for you but it's difficult to know what's going on without being there and knowing what tests have been completed. Heat from a relay is not uncommon but again, how much heat is too much? Try changing the relay. Bad connections are a source of heat. That's about the only idea I have. Good luck.
I know this is a couple years old, but I'm having the same problem with my 2000. I've replaced the ICM 3 times. It will run and start for a few days to a few weeks then refuse to start again. I bought the same Napa part and it was fine for a few days then refused to start! Then today, after 3 days of no start, BOOM... It started. I'm so lost. Any ideas?
That is aggravating for sure. A common problem on these trucks is for the fuel pump to fail. In my case the fuel return check valve failed (which is part of the pump assembly) so while the pump was pumping fine, the system couldn't hold enough pressure in the rails for the truck to start. Also, these GM's will run without a cam sensor working but will have a hard time starting. Check both the cam and crank circuits for the correct signal. Good luck.
@@wyattoneable Thanks for the reply! I still have to hunt down the cause of the p1351 I'm getting too. I could have 2 problems then. Great.
Hey man sorry to bother you what's the name of the pard the U replaced I have a 96 Chevy and I'm having the same code problem
Miguel Estrada Ignition control module. Hope you get it figured out.
Mine gives me this code and backfires
