You must check to see if you have power at the fuel pump relay which is probable in a fuse box under the hood.

Fuel pump on 1994 caprice not pumping fuel. its a new pump. replaced pigtail harness and relay. checked all fuses and used test light to check wires connecting to fuel pump.


I've run into new pumps that didn't work. If there is power at the pump and it is not pumping, then the pump should be replaced, again (under warranty).

How much fuel pressure does a 1997 bmw 540i require


why are you asking the fuel pressure. It doesn't make sense, because once the fuel pump are failing, the car will stop and won't start. Tell straight what do you observe about your car, engine shaking, not enough power, or what, or need to scan or diagnose your Bmer to solve your problem. ok

I have a 1995 540I bmw..fuel pump doesn't run....pump ok..fuse ok...relay ok(if Im checking the correct one) can you help


if you have 12 volts at the pump and it doesn't run it's the pump.
If you have 12 volts at the pump it means the relay is doing its job and the fuse is ok

remove the pump and run 12v to it directly from the battery to test the pump.
