First Start :
Fuel pump not working when ignition turned on. Fuel pump works when connected to an independent battery. Wiring to pump is ok. Questions: Shouldn't pump come on with ignition? Shouldn't pump stay on while vehicle running? Could it be s relay? Where is the "Main Relay." Other possibilities..., Thank you. (IMG:style_emoticons/default/wacko.gif) |

Just been thru the B.S.with my car,pretty much same situation,replaced the fuel pump relay and the pump worked for a short time,finally turned out to be the power relay for the F.I.,I should have known better but didn't expect 2 relay failures in a row (IMG:style_emoticons/default/sad.gif) .
These parts are old now and have done many cycles and the contacts inside get burnt and stick at least that what I found when I opened them up. Don't dismiss a bad ignition switch,however you will most likely have other stuff not working when it fails. |

The relay board is flat, in the drivers's side corner of the engine with the black plastic cover yeah? Can you determine which relay is which? Also, two white fuses are there. I'll check it all out, and thanks so much. You guys are all I have and I want to get this car running! Thank you, Chip/Utah |
