I have a 6.0 powerstroke that I just replaced the head gaskets on and now it won't stay unless I shoot it with a shot of ether then it will run fine
I have 800 psi of oil while it's running at the icp
my ipr is reading right
any other suggestions?

 

you have a leak in the hpop system somewhere and right now it's causing a no start but will start with ether.with the ether it can over ride the leak but you will fined as the truck warms up it will eventually shut down perhaps going down the road or in the drive way.

 

Figured it out was the wiring harness
