Urgent-Fuel Problem Help Needed 1994 Firebird formula.
I have been having fuel issues fuel pressure dropping and sometimes my pump wouldnt even prime. I tested the pressure and sometimes it would run totally perfect and drive fine but at WOT it would drop as low as 20. Sometimes I could not get a but 32 prime 20 prime and the car would run at 10 psi bogging. I jumped the pump prime connector on the pcm with 12v and was not able to hear the pump or get a prime. Now as the car sits bypassed to the pumpp prime connector or not I can not get the pump to come on. Heres where it gets tricky... If i test the rear pump connector under the car I do not get any power/ voltage unless I bypass and supply power via pump prime connector.
Do I have a bad connection somewhere whats going on?

I had the same problem on mine this week. My friend jacked up my car and smacked the gas tank and the pump came back to life but not for long. So I replaced the pump and all is better wit the fuel system atleast.
