How do you test 2004 dodge stratus fuel pump?
You will need a helper. Have your helper sit at the steering wheel while you listen at the fuel filler door with the fuel cap off. Have a helper turn on the ignition without starting the engine. You should hear the fuel pump run for a few seconds and then shut off. If you do not hear it run either the fuel pump is the defective or the fuel pump fuse is blown or the relay is the defective. Check the fuse in the relay first. If they are good the fuel pump needs replacing. If you hear the pump run then you know the fuse and relay are good. But this does not necessarily mean the pump is actually pumping fuel. In order to determine if the pump is actually pumping fuel you will need to run a fuel pump pressure test at the fuel rail. What ever you do make sure your replace the fuel pump filter if it is replaceable.

You can test it to see if it is actually running. Have someone stand at the fuel filler door with the fuel cap removed while someone else turns on the ignition without starting the vehicle. The fuel pump should run for a few seconds and then shut off. If you do not hear it run you might have a blown fuse or defective fuel pump relay. If so check the fuse and fuel pump relay. If it does run it still can be defective, it may just be running but not pumping fuel. The only way to know if it is actually pumping fuel is with a fuel pressure test. This is done at the fuel rail with a fuel pressure gauge.
