1997 gmc yukon fuel pump not cycling

Wire the fuel pump direct from the battery and see if it'll start up-if so check the computer controlled of the fuel pump relay circuit-

i'll give that a try in the morning thank you.

Okay-let me know your findings

really quick would a bad oil pressure sensor cause this symptom also by not activating the pump?

I was fixing to give you that-when the fuel pump primes the system before the relay deactivates and fires up and then dies we can blame it to the fuel pump and oil pressure sending unit-

When the engine fires up-the FPOPS-powers the fuel pump at all times-Good Luck

alright im a little embarrassed because i checked all of the fuses with a multimeter and again visually. i found that the ecm b fuse was blown when i checked them again yesterday. i replaced the fuse and as soon as i turned the key everything cycled like it was supposed to. the yukon started and runs fine now but it was a diagnostic nightmare to end up finding something so simple. i did short the pump to power to test it and it ran fine, i checked the wiring and fuses all seemed to be fine but the one that was blown showed okay during a continuity test with the multimeter. but its running now and i thank you for your advise.
