Question about 1991 Oldsmobile Ninety Eight Regency
More likely the fuel pump.........check for power to the pump on the gray wire at the fuel pump connector at the tank.(wires from the tank)You should see a prime cycle voltage as you turn the key on...if the key has been off 15 seconds. If you see a test light, light.......change the fuel pump.
Tip....a lot of relays are the same in the relay center....switch the fuel pump relay for one of the (same) others to test it if needed.
Before you do this....sit in the car and turn on the key to run.....not start.......do you hear the pump do it's prime cycle?
Total silence means.......in 99% of cases...a new fuel pump is needed.
If you hear it.......no pump should be needed....look elsewhere first.
