NEED YA"LLS INPUT

[96whitehouse]

Alright I need everybody's input on what ya'll think it could be. So this is whats going on with my truck it shut down on my about a month ago when i started it back up it would run for like 30 to 45 seconds and shut back off. So I took it to a diesel shop and they said it was the low pressure oil pump, so I said fine go ahead an change it. They changed it but it still would not start and they aint know what was wrong, but the guy said he thought it was the PCM. On that note i took my truck from him and said i would put the PCM in myself so I replaced the PCM still no start. I got tired of F***ING with it so i took it to FORD and they called me today and said my truck don't have low pressure oil, so what has me f***ed up now is did that shop change the oil pump in the first place. And if they didn't what would ya'll do if this happen to ya'll. Or do ya'll have any other idea of what it could be cause if it aint the low pressure oil pump the only other thing I can think of is the motor is screwed but could be wrong have been wrong before. Thanks for you inputs in advance.

Truck is a 1996 F350 7.3 and the mods is in the sig.
