1997 Chevy cavalier fuel pump relay readin 25v on pin 87?
Fuel pump started making lower sounding noise when priming and wouldn't prime after a while. Let is set over night and it primed once and ran it for an hour, but didn't prime the rest of the day. Did this same thing for 3 days, but now it never primes. Checked fuses and swapped relays and tried to jump pin 87 to 30 and still would not prime. Testing the fuel pump relay socket I get strange readings on pin 87, which I believe is the input pin from the battery, pin 30 is output. When I tested the AC relay socket I get 12V on pin 87, but get strange readings like 25V sometimes more on pin 87 on the fuel pump relay socket. I know what a job it is the replace the in-tank fuel pump, I replaced it 4 years ago. This time it has a full tank of gas. I'm almost sure the fuel pump has gone bad but want to fix the cause of the problem this time. I don't want to ruin another fuel pump and these readings are worrying me. Any ideas?
Why is your fuel pump not getting power to it?
If your fuel pump is not receiving power it could be because a fusible link or fuse has blown, the fuel pump relay is not switching or the brain (ecu) is not triggering the fuel pump relay. To test it, pull the fuel pump relay and locate the coil prong and switch prongs on the relay. There is usually a diagram on the relay or the prongs are numbered. Prongs 85 and 86 are for the coil and prongs 30 and 87 are for the switch. Figure out ( carefully ) wich leads on the relay mount correspond with the prongs on the relay. Use a jumper between the switch leads ( 30 and 87 ) and have a friend stand by the fuel tank. Turn the ignition key to the on position and your friend should hear the fuel pump start to run. Don't run the pump for more than a few seconds. If it does not come on you have probably blown a fusible link or fuse. Remember to remove the jumper. If it does come on test the signal from your brain by using a volt meter or test light between the coil leads ( 85 and 86 ) on the relay mount. Have your friend turn the ignition key to the on position and the light should light up ( or the volt meter should show voltage ) for a few seconds then shut off. If this does not happen there is no signal from your ecu. If it does happen replace the relay.

switch it with a relay that works, like your horn relay or simulate the relay with fused jumper with 12 volts from your battery. 87 on your relay is your out to the fuel pump. putting 12 volts to the point of contact where 87 would be should start your fuel pump.
