Found and Fixed! 1994 7.3 Powerstroke Crank No Start

[@timrowe5308]

Been having the same issues with my wife’s 96 F250 7.3 .. After watching this video the problem was solved… the wiring to the IPR valve was old and broken…. Thanks for the awesome video… Subscribed.

[@cisforcars]

Absolutely awesome news!! Thanks for the sub. We tend to lean on the funner side on the Channel, but knowing we can help out once and a while too means a ton!! Happy travels!

[@tjobrian7574]

Thank you soooo much for this video!! I was getting ready to fire the parts cannon, which I cannot afford. I watched this video, and tried shaking the wires where you showed, guess what.... No parts cannon! She fired right up! I hope more people see this video and are helped by it!

[@cisforcars]

Heck yeah, that's what I like to hear!!

[@powerstroke7400]

Good information! My truck is a 97 7.3 270,000 miles. Been a fantastic truck!

Going to try this on my truck. These exact symptoms are happening. Thanks man!

[@cisforcars]

Good look, man! I hope it's as simple as this!

[@All7.3FordTrucks]

Thanks for covering this topic. Also I love your OBS Ford!

[@cisforcars]

Not a problem, thanks for the kind words!

[@Godspln4me]

My 94 did the exact same thing 2 years ago.I would replace the cam position sensor and it would run fine but about 2 weeks later it would do the same thing again.I had just replaced the cam sensor and it died but started back up so I popped the hood and it was dark on the side of the highway and I saw a spark.the 2 wires between the ipr and the connector were both bare and would touch intermittently so it was kinda like how you found yours.I bought the pigtail from Riffraff where I buy most of my stuff for the 7.3.that was a really good video I didn’t think of making a video because I was thinking it was just my truck having trouble.😂

[@cisforcars]

It can be a HUGE pain to chase electrical sometimes! All of us powerstroke people are in this together! Lol. Thanks for watching.

Love it, keep ‘em coming

[@dougmartin6717]

Very relevant to me. Almost a year, off and on learning the basics of this engine, and why it cranks but won't start. I've replaced the HPOP which I likely didn't need to do. For a good pressure test, one needs to activate the IPR regulator which I hadn't done. So with no activation it was delivering no pressure. Once activated, I got 3000 PSI. Not a HPOP issue. Never any exhaust smoke, an injector buzz test yielding zero noise and came to find that my IDM was getting zero power from the PCM. I am now down to finding whether there is a harness problem like here, either a disconnect to the IDM or some other short that tells the PCM not to activate the IDM, or whether the PCM is blown. Stay tuned.

[@cisforcars]

Awesome. It takes time to learn them, but once you do they're fairly simple. You'll be a pro once you're done! Good luck to you, sir!!

[@The_Bored_Farmer]

Have you found out the issue yet?

[@dougmartin6717]

@@The_Bored_Farmer No. Bad to worse. I went through every pin on the PCM connector. No shorts. Reasonable looking resistances. So it all looked ok to plug in the new PCM bought from Rock Auto, which was supposed to be a match for my '97 truck. Few things worked right. No 5V ref, a couple sensor errors, and still no power enabled to the IDM. The kicker is that since they sent me the wrong part for this truck, they will not accept a return because I tried installing the wrong part for this truck. Rock-Off, FuckAuto!! I'll return it anyway, as a failed core. I don't know where to turn. I've been working on this for 11 months and am about to conclude that this F-250 7.3L diesel, with less than 100k miles on it is destined for a landfill. Pure garbage in an era when Ford made nothing but garbage. Is there no one who can make its garbage electronics work??

May God Bless you for making this Video I Had the Exact same Problem. Thank you

Thank you for the kind words!! I'm glad it helped my friend!

Maybe that’s not much fun but it’s been fun watching you (only because I’ve been in the same position)😂

[@cisforcars]

Hahaha, hey I get it!!

[@chriswablington7118]

I’m having the same issue in my ‘97. It cranks and starts fine one day, next day it cranks/no start and no smoke. Thanks for the heads up. I’m gonna investigate the IPR. Don’t go and sell yours. You’ll hate yourself later

[@cisforcars]

Definitely a great place to start! And I know, I've been on the fence about selling it a few times, but I always come back to reality and give my head a shake. Thanks for watching!!

[@andrewgomez7960]

When you do the clutch make sure you replace the sleeve that the throw out bearing rides on. Get an oem or equal. Also rock auto sells the fuel bowl cheap it comes with all the wires that you had to replace because of leaking diesel. Last burned out pins at the connection for the under cover harness are common. You can splice pigtails in or buy a small kit that comes with new plastic connectors and metal clips. It also has the metal pick to get the wires out if the connector. The leaking diesel on the back of the heads is because the orings are worn out where the fuel lines connect to the heads. When you pull the transmission you will see them replace them then.

[@cisforcars]

Thank you for the insight! I'll make sure to look into all of that!

[@arturo5819]

I had the exact same problem a few years ago with my 97. It was driving me nuts till I just started wiggling wires and found the problem

[@cisforcars]

Bruuuutal. Glad you found it eventually!

[@vancedurham5310]

Thanks for the info, i got my hands full with my 1997 7.3. Where did you get your headlights from? Nice.

[@cisforcars]

Same sort of issues? These are just your cheap ebay specials, the originals were fogged up and faded terribly.

[@alwalkr1118]

Way before i went to mechanic school i was always taught to remove all jewelry before working on anything.

[@cisforcars]

Absolutely! Great point!

[@ke9527]

Thanks man.

[@luisvega_marketingdigital5082]

Greetings, I have a 1995 Ford diesel power stroke 7.3, it starts perfectly but it doesn't want to accelerate and I changed the accelerator pedal and the computer and it remains the same, what could be the cause? I need your urgent help, it is a crane and it is my method of working and I have been on foot for 3 months.

[@cisforcars]

Oof, yikes. That's a hard one. There's some really great flow charts out there for diagnosing a 7.3, and are a great place to start. Remember not to throw parts at it though, always confirm your issue if possible! That being said, if it only happens when you go to accelerate, check the tin nut on the back of the IPR, the solenoid and sensor on the back thr HPOP, under your fuel bowl, front of the valley. It may be loose enough that under acceleration, it cuts off. I'd start there. Good luck, though! I hope you're able to get it soon.

[@chriswablington7118]

If you’ve never cleaned the sludge out of the HPOP, I would definitely do it. Mine was very sluggish until I vacuumed all the sludge out and replaced it with fresh oil. I was skeptical it would help before I did it, but it made a big difference in acceleration!

[@mobiusprolix8454]

Cam sensors can do it too

[@richarddodds9326]

I went to diesel engine mechanic school before they had all them eec.I have seen a drop of water shut em down

[@Chavez.16]

Did you happen to have a no ‘wait to start’ light as well? I’m having this issue right now my truck started fine this morning and while warming up it shut off then crank no start and no smoke out the tail pipe, but she sat for about 10 minutes and the wait to start like came back on and started again, then shut off about 30 seconds later then again crank no start and no smoke out the tail pipe

[@cisforcars]

To be honest I don't remember, now.. But everything else you've described is sure similar. I would check this, and then maybe for fuse 22 being blown but maybe still making a little contact? Good luck!

[@ChristopherBrown-s5h]

Link to the harness you purchased?

[@cisforcars]

It's an Amazon special, but it had the best reviews and the build quality seems fine. It also utilizes the newer style locking mechanism, which I like. www.amazon.ca/MOTOALL-Connector-Powerstroke-Injection-Regulator/dp/B07JF2ZSWS/ref=mp_s_a_1_2?crid=CSQTGSOP07L0&keywords=7.3+powerstroke+ipr+harness&qid=1694532116&sprefix=7+3+powerstroke+ipr+harnes%2Caps%2C193&sr=8-2

[@anhyzerkaiser]

How's the truck been running since then?

[@cisforcars]

It's been perfect! Clutch will be going in soon, she's currently resting for a month or so.

[@beatbeat4378]

Where you able to do injector buzz test when it wasn’t working?

[@cisforcars]

Unfortunately no! That's the problem with the 1994, and some early 1995 Powerstrokes. The PCM would need a refresh to properly run an OBD scan tool. So this truck has very very little in the way of digital diagnostics. Being said, I'm sure there's a way to do it without this, but I don't know it.
