disconnect the fuel pump at the tank (connector) get a test light or voltmeter and check for voltage at the pump with the key on in start position and (or) leave key on and stick something in the mas air flo sensor (big door that opens) make sure you are getting juice at fuel pump, if not follow the wire back till you find where it ends ( Im not sure but I think it is connected from relay that is controlled or turned on and off by ecu ultimately Hope this helps
