99 Trans am No start need help! Hey guys i have a 1999 trans am 5.7 6 speed WS6 with 15,000 Miles on it the other day i was driving parked to get my mourning coffee came back out and no start. i tried switching relays checking fuses and everything was good. I checked to see if i could hear the fuel pump prime and nothing, So i changed the pumped with a OEM replacement by ACdelco. car started and ran fine untill a few days ago the same problem occurred. Checked fuses relays and everything is good. again the fuel pump doesn't Prime when turn the key on and no pressure at the rail. I am at a complete lose here. any help would be greatly appreciated! thanks guys!

I had something similar. Put a pressure gauge on the fuel rail. I changed the fuel pump relay and then the pump $$$$$$$$$$$$$$$ Not happy.Changed fuel pump relay again with a GM part not the crappy PB's part. Car's now fime for 10 days and counting. You can jumper past the fuel relay to be sure.
