My 96 suburban won't start. My fuel pressure read 52-54psi and i'm not sure what the specs are but if to low, what could that be? If the pressure is correct what else other than the usual answers could cause this

I've answered your question earlier and you keep asking. Why don't you do what I've suggested and comeback with some testing results-there's no quickie fix it involves troubleshooting/diagnostics to get back on the road-Your fuel pressure should be 60-66 psi, which part you don't understand from me-

You don't trust my answer go somewhere else bcuz you ain't gonna get it from here in quickie fashion. I've told you already your fuel pressure is too low-fuel pressure is very critical. You sure you know what you doing? Bcuz I do-Wrench take over as you wish -Good Luck

I APOLOGIZE FOR CURSING AND AS YOU CAN SEE THE OTHER GUY ASKED WHAT SIZE ENGINE IT WAS, SO I TOLD HIM. THEN I LOG ON AND SEE WHAT YOU POSTED AND GOT UPSET. I KNOW ALOT ABOUT CARS BUT I DON'T KNOW EVERYTHING AND THAT'S WHY I'M ASKING FOR HELP. IT'S NOT THAT I DON'T TRUST YOUR ANSWER. SORRY FOR THE MISUNDERSTANDING AND THANKS FOR YOUR HELP

Ras is 100% correct. Your fuel pressure is too low for that engine.
