    Q:
    How to check Fuel Pump on Buick LaCrosse? Posted by Lecil P.
    A:
    The fuel pump check involves listening for the whirring sound made by the fuel pump when the ignition key is turned ON. If the pump does not come on, check the fuel pump fuse, relay, and wiring. If they all work, the fuel pump is likely defective. If the pump runs continuously, the PCM may be defective. Begin the engine and the gauge reading is compared to the proper pressure specifications. If the pressure is too low, there may be a faulty fuel inlet strainer or blockage in the fuel lines. If it is too high, replace the regulator. The key to the engine must be in the OFF position when checking the psi level. Any fuel leaks should be checked for and the system should be cleaned up.
