You can Select Your Vehicle to check if 15904477 fits your vehicle.

Fuel pump operation check consists of listening for the sound of the fuel pump when the ignition key is turned to the ON position. Turning on the fuel pump fuse in case it doesn't come on, examining the condition of relay and wiring are ways to check this. In case all these are right, either the fuel pump may be defective or PCM can be faulty. To test the fuel pressure one could use a gauge that connects to Schrader valve test port found on fuel rail. The fuel pressure must be within specifications; if not, it indicates that probably there is a clogged filter, some blockage in the system or perhaps a bad fuel pump module. The engine should lose no more than 8 psi during 5 minutes after being turned off, anything more could mean that there is a leaky injector, leakage from a fuel line or in fact an incorrect functioning check valve in the fuel pump module. Lastly, always ensure there are no gas leaks before starting the engine.
