    Number 3 pin @relay sends power to the fuel pump
    (green wire), pin 2 (green/red gets grounded by the fuel injection power train computer, pins 1 AND 4 GET POWER THROUGH THE CIRCUIT OPENING relay, and EFI relay. Fuses in the circuit are, 10 amp fuse marked IGN and 20 amp fuse marked EFI.
    There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
