After having driven my car all afternoon yesterday I went to go out with my wife last night and the old bird wouldn't start. I quickly discovered it was a fuel problem, as in there was none coming out of the injectors. They were clicking away, but no fuel coming out. I checked the ECM fuse, and it is good. I checked the fuel pump relay with a 9V battery and it was good too. However when you turn the key to KOEO, the pump doesn't prime. Unfortunately most of my tools are at work or I might have more info. What fuse does the fuel pump relay get the power that it sends to the pump? The coil side of the realy gets power from the ECM, but what about the load side? My wiring diagram show a 10A (or was it 20A?) fuse that I can't find. The SES light doesn't bulb check either. I'd hate to condemn the ECM, but it is starting to look like that might be my problem. Thanks for the input guys.

Check the Oil Pressure Sending Unit - if it goes bad, no current to pump.

Should be located above oil filter. About a $30 replacement.

FYI - they can also go bad causing constant current to pump, whether key is in car or not.

 

Hey, you live in Cary, cool I live down the street in Apex.

Yeah, I'll try to check that too tomorrow.
