Won’t start after running for 30min

[DVafghan]

This motor was pulled, cleaned, and rebuilt. Grounds were replaced because after 15 years they looked shotty.

Make sure the injectors are working. You will need a noid light, or a remote start and a mechanics stethoscope (to listen for ticking at the injector)

I'm just going with the basics.. don't overlook the basics.. I'm just trying to help, not saying you made a mistake.. But check those grounds anyway.. Maybe you forgot to put one back in place.

I’m not saying you are but I’m just filling in the info that’s needed. All grounds were replaced with new grounds and they all were checked for being in good contact.

Was the problem there before the engine work?

High mileage  and no power to haul a 7k lb trailer. Wanted cams only but the mechanic who did the cams blew the motor so we replaced all internals and it’s now a 6.0L stroker motor.

Did you have any problems before this?
When was the first time you had the problem?

It hesitated while pushing the gas pedal and had a crazy and couldn’t find misfire problem. Now all besides fuel pressure issue it runs great.

Good luck with your fuel pressure issue.
