No power to fuel pump '93 metro - Fuel Economy, Hypermiling, EcoModding News and Forum

There is no power getting t the fuel pump relay. I checked all the fusees under the dash and the ones next to the relays in the engine compartment. Is there a fuse I am missing? or does this sound like a short. The fuel flow stopped when i was driving 30mph in town and it was abrupt.

Was their any recent work done to the car? You cannot hear the fuel pump kick on at all?

No sound at all. I checked and there is no power getting to the relay. I am just don't know that much about electrical problems yet. I must be missing something simple. I think this car was in a flood at some time before i bought it, I have found rust in strange places and corrosion in some of the connectors. where does power go before the relay in this car/

Thanks a ton for any help!

Thanks a lot Johnny, I am going to go and get on it right now!

well, I keep blowing a fuse. I checked and there is continuity from the computer to the relay and from the relay to the fuel pump. So I am not sure why I am blowing that fuse, maybe a bad ground?Would it be a bad idea to cut the existing ground wire and re ground the pump directly to the body?

Would i be blowing that fuse because of a bad relay? still doesn't explain why I was not gettin power to the relay( blown fuse), but why does the fuse keep blowing?

I am tired and proly not making complete sense...

Thanks for any help!

It would never hurt to add a known good ground.
