Fuel pump pressure test.
First off check the fuel pump fuse to make sure it is not blown. The best thing to do is just replaced the relay to make sure that is not the problem. If you can hear the pump run with the ignition to the on position, engine not running then it may be good. But it is possible the pump is running and not pumping fuel. A fuel pressure test at the fuel rail will verify the condition of the pump.
Test for a broken wire between the fuel pump and power distribution box. Check for bad connectors also.
Fuel pressure test at the fuel rail.
A fuel pump pressure test could determine the condition of the fuel pump and fuel system.
You can test your automotive mechanical fuel pump with a diagnostic tester. The diagnostic tester can tell if the fuel pump is operating properly.
No noise from pump when you turn the key, runnability(starving for fuel) problems, dies out, no start, power to pump (check with test light ) but pump won't pump. The car won't start properly.

Where is the fuel pump fuse and relay on 1994 BMW 525i and how can I test to see why my fuel pump won't work
With a fuel pressure test at the fuel rail.
Fuel Pump fuse, relay, fuel filter, and all connections. A fuel pressure test will verify a defective fuel pump, or if it is simply not running, and has current to it.Fuel Pump fuse, relay, fuel filter, and all connections.

No, the fuel pump relay engages and sends voltage to the fuel pump. The fuel pump requires 12 V DC to operate properly. A fuel pressure test will verify the condition of the fuel pump.
is this a question.? do you want to buy one. find one on car. find one in car. do you what to test it. did i prime your pump.... hahahahaha
A GOOD FUEL PUMP PRESSURE IS NEEDED
Have a fuel pump pressure test done.
If that is throttle body fuel injection, there is no fuel pump test port. You have to fabricate with some fittings and tap into the fuel line at the fuel filter.
Fuel pressure test. First thing to do is replace the fuel filter. If that does not help, then test the fuel pump with a fuel pressure tester. If you can't hear it run for a few seconds when the key is turned on, either the pump is bad, or the fuse is blown, or the fuel pump relay is defective. Even if you hear it running, it may be so weak as not to work properly.
You can test the fuel pump by touching the positive wire on the positive post of the battery. You will need to ground the ground wire.
I believe this question is related to fuel pump pressure testing...... these test are done by scanning ecu
If you have power to the fuel pump and it will not run it is defective. If it runs but a fuel pressure test verifies that the fuel pressure is low and you replaced the fuel filter then the pump is defective.
Run a fuel pressure test with a fuel pressure gauge connected to the fuel rail.
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.
Fuel pressure test. If you cannot hear it run for a few seconds when you turn the ignition on without starting the engine, then check the fuse and fuel pump relay. If it runs but you are not getting enough fuel, replace the fuel filter. If you still have the problem have a fuel pressure test run to see if the pump is weak.
A fuel pump pressure test could determine that.
