2002 7.3 F250 just died on me

[lance125]

Was driving with no problems being reported ( check engine light, low fuel light) nothing. I had about an 1/8 of a tank of fuel and was on my way to get more, when it just stopped accelerating and then seconds later the engine just shot off. As I thought I was a low fuel thing even though the low fuel light was not on, I got some and put it in and was unable to get it re-started. A mechanic that I know who is not a diesel guy hooked it up to his dio and said that it was throwing an PCM code. My question is will the PCM cause the truck to just stop mid run. It still felt like a fuel flow problem. Any thoughts guys

What exactly was the code?

1/8 tank? That is NEVER a good idea. I would put 10gal in the tank. Turn the key on, listen for the pump to come on. AFter 15-20 sec, it should shut off, turn the key off and back on every 20 seconds for about 3-4 times. Open the fuel drain valve on the bowl and turn the key on, fuel should be rushing out. Turn key off, close valve and try to start the truck.


Also, check the batt voltage to make sure you didn't drain them trying to start it.

we opened the fuel drain and it seemed to be good pressure. The turn over seems strong enough to start it. Yes I know getting to 1/8 is a bad idea. I never let that happen, but I got stuck out in BFE and well stuff happens.

do you have a programmer in the truck? he might be seeing pcm error code that those usually leave. Get the code numbers from him and post them here

[lance125]

No I do not have a programmer in it, I will have to get the codes from him. He just told me It was the code for a PCM, and he tripled checked it.

cam position sensor maybe???

[lance125]

And the cam sensor will cause the truck to stop mid run

This is what happened to me recently -

Truck headed to the Shop

[lance125]

Ok so I read your shop visit and the issue you had sounds like what I was going through. I just talked to a diesel mechanic and he said that even with a bad PCM my truck should start, will run like crap but it should start. Thanks for linking your issue for me. I guess thats what I need to start with, and see what happens from there.

[lance125]

Ok so after what SuperCruty and others that I talked to have said it looks like I need to start with getting a PCM. I kinda have an in on getting one from Oreilly's for a good price and have been told I can change this myself so I guess that what I will do. Any other thoughts before I dive into this tom. Thanks Super and others for the advice.
