7.3L Issue

[Worstenemy453]

Truck will start fine and run. 2002 7.3. Truck has 180K miles. Completely stock.

When the truck gets hot, it wont start anymore. Will start fine when the motor is cold. We let it run for a few, shut it down and it wouldnt fire back up.

Replaced the CPS and still have the same issue.

Thinking Hpop or IPR.

Any input or anything ?

I think you are on the right track. Time to watch ICP at hot start up.

It's all guessing without numbers. Have you been into the hpos recently?

NO, we got it, ran the AE on it, saw the CPS was kinda iffy and changed it. We havent touched anything else on it.

Get the info from AE. Watch your ICP and IPR and report back. I'll almost bed you have a blown oring in your IPR.

Injector o rings. You can pull the valve covers, and crank it I bet you will have oil coming out around an injector. My 97 did this last year just like that.
