1. Turn the key to the "On" position: This will power the fuel pump without starting the engine.
2. Listen for a humming noise: The fuel pump should make a humming noise when it is running. If you do not hear a humming noise, the fuel pump may not be working.
3. Check the fuel pressure: You can use a fuel pressure gauge to check the fuel pressure at the fuel rail. The fuel pressure should be within the manufacturer's specifications. If the fuel pressure is too low, the fuel pump may not be working properly.
4. Check the fuel filter: A clogged fuel filter can restrict fuel flow and cause the fuel pump to work harder. If the fuel filter is clogged, it should be replaced.
If you suspect that the fuel pump on your 1998 Plymouth Breeze is not working, it is best to have it diagnosed by a qualified mechanic.
