check the the pump pressure at the rail
how do i know the fuel pump is going bad in a 1998 ford expedition eddie bauer?
If the fuel pump becomes noisy you can rest assured it is going bad. But, the pump maybe going bad and not make any noise at all. Anytime you have a problem with fuel delivery, first thing to do is replace the fuel filter. After replacing the fuel filter a fuel pressure test will verify the condition of the pump.
When a fuel pump is bad the vehicle will not start. A fuel pump that is going bad may cause the vehicle to shut off while going down the road.
Noisy pump, hard starting, stalling.
You just don't know until a mechanic tells you.
Hard starting, stalling and eventually it simply will not run. Change the filter before assuming the pump is bad.
Bypass the relay and if the pump works the relay is bad.
no...if the pump is indeed going bad then it will not be able to properly pump enough fuel to your cars engine..better have a professional look at it soon.
Noisy fuel pump, stalling, or engine will not start and you have no fuel pressure.
A fuel pump pressure test could determine the condition of the fuel pump and fuel system.
Blown fuel pump fuse, defective fuel pump relay, bad fuel pump, or clogged fuel filter.
It is a fuel proplem. It may be a weak fuel pump, bad float in the tank, or a clogged filter. I would put my money on the pump going bad. It is a fuel proplem. It may be a weak fuel pump, bad float in the tank, or a clogged filter. I would put my money on the pump going bad.
