1997 f350 7.3L won't stay running!!!

Was driving down the road and the truck just died, got it towed back to my shop to work on it. Saw fuel in the valley of the motor so i replaced the fuel pump because that was leaking, new fuel filter and new lines running from the pump to the bowl. Still won't run!!!

It fires up fine, but then dies. I can keep it running if my foot is on the pedal but it is very rough.

Any thoughts?
Thanks!

My truck was doing the exact same thing, pulled the codes, and it was the cps running intermittent. pull the codes to be safe, but im betting its your cps. $35 from international.
did you check the screen between the ipr and the fuel bowl? my truck also had a good amount of junk cloggig the screeen causing it to stall.

I checked the Cps and it was good, I have not yet checked the screen but I had to bite the bullet and take it to the pros.

I got tired of throwing parts at it and the truck won't pull any codes, I will let you know what it wrong with it when I get it back.

Thanks!

The experts figured it out!

The injector wiring harness must have melted down and caused my glow plug relay to short

It's going to cost me $1700 to fix my baby!!!

DAMN.... im not sure how much of a headache it would be to repalce those gasket/wiring harnesses on your own, but i think its very similar to just doing a valve cover gasket set on a (gas) v8, with the exception of having to plug in the wiring to the right injector/ harness connector.

they have any idea what might have caused it to start melting? seems wierd to just have melted down outta nowhere.

I think the connection came loose and shorted out, but the plastic on one of the connections was melted and burnt.

For the cost of an Auto Enginuity and parts you could have been way ahead of the game . Also changed out glow plugs and learned an awful lot about your truck, just my 2 cents.
