Best Answer

first have an assistant turn the ignition switch to the on position and listen for the whirring sound from fump pump, indicating pump is operating. If fuel pressure is in question you can install a tee fitting between fuel filter and fuel line and purchase a fuel pressure gauge to connect to the tee fitting. fuel pressure should be at 43psi with key on engine off, and 34 to 36psi with engine idling.
