    I have a trouble code of 22... fault in the throttle position sensor or the fuel pump relay.... I have the diagnostics figured out for the TPS but can someone tell me where the fuel pump relay is and what it looks like on our trucks
    the manual doesnt say and the wiring schematic shows the loom colors which are hard to trace... and no pics of where it is
    thanks

    This one is lying on the floor, you can find yours on the firewall just to the left of the distributor. You can't miss it.
