My fuel pump isnt priming when i turn the key on? It will start however after the oil pressure switch builds some pressure, but it will die soon after. Ive replaced the pump, the relay, filter, pressure regulator, oil pressure switch, and the fuse by the battery.. Any ideas on why it isnt priming? Oh and im getting a code 54 from my SES which should be a given. Any help is greatly appreciated thanks!

ditto.... wat he said.

can only be the pump relay or the pump itself.

Code 54 = fuel pump circuit low. If the pump and relay are known to be good, it could be some worn out or damaged wiring.

I just had this same issue with my car an after 3 fuel pumps,2 fuel filters later i rewired the fuel pump fuse an ditto now its primes everytime and fires right up.
I hope this helpd

When my TBI car had that problem it turned out to be the thick, 10 gauge wire that's part of the positive battery cable. It had corroded through at the side post terminal. I used a big eyelet connector to hook it back up at the battery post and it fixed the problem. Took me a whole day to figure out. The wire was still attached to the battery cable, so I didn't notice how corroded it was until I wiggled the wire a bit and it fell out of the battery terminal. I had already replaced the fuel pump relay too.
