Ok for a while now ive been gettin a code 54. Now lemme start off by saying, ive replaced everything, relay, pump, filter, oil pressure switch, pressure regulator, and everything but the pump seems to be getting power. Im completely out of ideas. The pump will not prime, but the car will "usually" start after some oil pressure is built up. Umm, i am getting power to the connector above my differential (CTK 120 i belive?) and the car will idle and run fine after it finally starts. If anyone has any ideas on why the pumps not priming, i tell ya, i really really appreciate it. Thanks

 

There is a small transistor in the ECM that goes out. This is easy and inexpensive to replace. There is a thread on the DFI & ECM board with pictures along with the transistor number to use. Search using my name as a post author, should turn up.

If you replace the ECM as the fix, let me know and I'll purchase your current one from you.
