A fuel pressure test done at the fuel rail will verify the condition of the fuel pump. Before going to that much trouble check the fuse, and fuel pump relay. If either one is defective the fuel pump will not function.

How can you tell if you have a bad filter or a bad fuel pump on a mpv?
The best thing to do is replace the fuel filter anyway. You will need to do it even if the fuel pump is bad, so you have nothing to lose. You can listen to hear iif the fuel pump is kicking on at all. If it is, just do the fuel filter. Its much cheaper and easier than the fuel pump. Then you can test the fuel pressure to see if the pump is bad after you replace the filter.

How do you tell if fuel pump needs replaced on 2001 buick regal?
If it is stalling or hard to start that is a symptom of a weak pump. If you do not hear it run for a few seconds after turning on the ignition without starting the engine, then either the fuse is blown, relay is bad or the pump is bad. If you do hear it running, then it may be weak or the fuel filter may be clogged. You may have to listen at the fuel filler door to actually hear the pump. Replace the fuel filter and then run a fuel pressure test at the fuel rail. If you have no or weak pressure the pump is bad.
