Check all your fuse, fuse for fuel pump is fuse no. 13 , relay for fuel pump is a solid state relays, constant control relay module located in the right hand front of engine compartment mounted to upper radiatior support, replace the control module if all fuse ok, 12V input wire black/yellow, output to fuel pump pink/black
Do this test first. With the drivers door opened in a nice quite area turn the ignition key to the ON position without starting the engine. You should hear the fuel pump operating for 5 seconds which is priming fuel to the engine. If not heard the engines oil pressure sensor is at fault. The third wire from this sensor links to the fuel pump to prime. When the engine reaches normal operation oil pressure range the computer shuts off that circuit and turns on the fuel pump relay for the pump to run. That relay stays on until you shut the engine off
Had the pump changed 3 days ago. Engine ran fine when restarted 4 more times. Now pump is not priming - as it did before I spent $286 to fix it. My car was built 8/1995. I don't see but one sensor and it has only one wire going to it - not 3. Is this a different setup? Oil pressure gauge is showing full normal pressure too. Any clues??? Car has 50,000 miles original FYI.
