Have fuel to pump but not coming out of pump to injecters?

The fuel pump may be defective or the fuel filter may be clogged. Replace the fuel filter if you hear the pump run when you first turn on the ignition without starting the engine. It should run for a few seconds. If you do not hear the pump running, check the fuse and the fuel pump relay. If you hear it run and after replacing the fuel filter you still have no fuel, the pump is defective and must be replaced.


I am unsure if my fuel pump is out or if the fuel filter is clogged how can I tell?

If you hear the fuel pump running, then start by replacing the fuel filter. If you don't hear the pump, check the fuse. A fuel pressure test will verify if the pump is good or not. It can also be a fuel pump relay or in rare instances a defective ECU.

How to tell is its fuel filter or fuel pump?

If you turn on the ignition without starting the engine you should hear the fuel pump run for a few seconds. This is a good indication the fuel pump is good but not 100% positive. A bad fuel pump can run but not pump fuel. If you hear it for run for a few seconds just replace the fuel filter to make sure it is not clogged. If it still does not pump have a fuel pressure test run to verify the condition of the pump.

Is there a way to check to see if a fuel pump is bad if fuel pump is in the tank?

You can have someone turn the ignition key to the on position without starting the engine while you listen at the fuel filler door with the cap off. You should hear the pump come on and run for a few seconds then shut off. If you hear nothing check the fuel pump fuse and fuel pump relay. If both are good the pump is defective. If you hear the pump run that does not necessarily mean it is actually pumping fuel. A fuel pressure test at the fuel rail well verify the condition of the pump.

How to test for bad fuel pump or fuel filter in a 2001 BMW 325i?

First just replace the fuel filter as it is a maintenance item that should be replaced regularly. If you hear the pump running when you turn on the ignition without starting the engine, that means the fuel pump relay is OK. If you do not hear the pump suspect a bad relay or fuse. If you hear the pump, and you still have a problem, you may have a weak pump.

Fuel pump?


What else should i check after replacing the fuel pump if the truck still wont start?

Assuming you have spark, when you turn the ignition key on do you hear the fuel pump run for a couple seconds? If not check the fuses, fuel pump relay and wiring. If you do hear the pump run check the fuel pump pressure, it may have a fuel pressure regulator problem.

How do you check to see if the fuel pump is working on your 1983 Cadillac sedan deville?

Get a helper to turn on the ignition without starting the engine. At the same time you listen at the fuel filler door with the fuel cap off. You should hear the pump run for a few seconds and then shut down. If you do not hear the pump check the fuel pump fuse and fuel pump relay. If they are good the pump is defective. If the pump runs and you are not getting fuel to the engine either the fuel filter is clogged or the pump is running but not pumping fuel. Replace the fuel filter and proceed from there.


What do you do when you put new fuel pump on and new filter on and you don't get fuel?

Should you be able to hear your fuel pump run?

Yes, but you will sometimes need a helper. Try sitting in the vehicle with the radio and blower motor off, all windows rolled up. Turn on the ignition but do not start the engine. You may be able to hear the pump run for a few seconds and then shut down. If you do not then open the fuel filler door and remove the fuel cap. Have a helper turn on the ignition while you listen at the fuel filler opening. If you cannot hear the pump check the fuel pump fuse and fuel pump relay. If they are good your pump has more than likely failed. If all is well and you hear the pump either the fuel filter is clogged or the pump is running but not pumping fuel. A fuel pressure test will be needed to verify the condition of the pump.
