Fuel pump problems:

03-07-2011, 07:09 AM

Parked the car Friday afternoon, went to start it this morning to head for work and it just turned over and over. After dropping the "WTF bombs" I get out and look under the hood. I've come to realize my pump isn't turning on. I jumped the fuel relay and my pump fires up. I've replaced the fuel pump about 1 year ago. Since my car is an earlier model do I have two pumps? the drivers side (replaced) and the intank one? I replaced the relay with an unconfirmed working relay, but I doubt both relays are bad Where should I turn this investigation towards? This is the first time this has happened.

Thanks,

I found that the connector on my late model (in tank) pump was not maintaining good connection. Something to check.

ICV only powers on when I jump the relay. I unplugged the ECU in hopes of resetting it. I'd like to have some more suggestions please

IMO replace all 3 of those relays - main, FP, and O2. It's amazing how many headaches/gremlins can be caused by a 25 year old relay.
