Does this car have two relays for the fuel system a main relay and fuel pump relay? Where are they located? I am not sure I have located them yet to check them. Can you send me a wiring diagram on the relays and fuel pump? Dose this car have a fuel pump check connector? If so can I jumper wire it to see will fuel pump run?
