Diagnose a bad fuel pump

Basic fuel pump diagnosis.

If a fuel pump is suspected to be bad and dont have a fuel pressure tester or any other fancy tools, maybe atleast you have a rag and small screw driver.
1. turn the key on and listen to the pump makes noise, then turn the key off. Do this atleast 3X.
2. Some vehicles like dodge caravan, on the fuel rail, located is the test port looks like this picture

 3. Remove the cap and press the valve core located inside the port. A fuel should squirt out the port. Use the rag to catch the fuel.

Note: A Squirt is enough to start the car. If still in doubt, crank your car for about 5X then remove one spark plug, it should be wet with fuel. If dry and no squirt come out the test port, then for sure you have a bad fuel pump.
