Question about 1994 Buick Park Avenue

1 Answer

Change fuel pump on 94 buick park ave....after market part had no polarity markings....possibly a rotated pump 180 degrees and installed reverse polarity...i need to know which wires on harness go to pump and which go to the sending unit. I am planning on making junctions at harness rather than dropping tank again. I have a blk,purple,gray,then gray/white at harness in that order. Can anyone help me out?? Pump runs with no pressure so i am assuming it suctions rather than pumping

Commonly submerged in the fuel tank. Some require the removal of the bottom rear seat, others need entire tank dropped to access.
If memory serves, you will need to drop the tank to access on the P.Ave.
Save yourself some time and pop off the rear seat just to be sure.

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

I would suspect a bad fuel pump. Fuel pressure test will confirm this. Can also be a clogged fuel filter, or bad relay.
