    yur fuel pump relay thingy is right up on the upper passenger half of the firewall, a little black box, if you have a 700r4 it will be next to that relay. /forums/images/graemlins/thumb.gif

    The little wire that comes off the pos+ terminal goes to the alternator, It must be hooked up to the + batt. Then where it bolts to a conector at the back of the alternator there is another red wire with a fuseable link that hooks up to it also. These wires must be connected or you wont get power to the ECM, ignition,and some other circuts like the headlights. Also your alternator wont work.
    Hook everything back up and it should start.
