Cat 3116 Diesel Engine Continued........
I have a 97 GMC 5 ton with a Cat 3116 engine, and it starts fine, but then will not restart after shut off utill its cold again. In researching, I've found this could be fuel pump, oil pressure pump, and maybe fuel injectors. Was wondering if you might know, or have a suggestion how to narrow it down cause I can't eeny meany and hope to change the right one before I've done all three. :)

Check your fuel shutdown solenoid, when you try to start hot there should be a noticeable click in the solenoid meaning it's energizing. This is if everything else on your engine is runnng normally.
