Vette's update made me go back and reread this topic. I had missed Michael's comment that he had tried it with the alternator wires disconnected and it still failed. This step
eliminates electrical noise so forget trying the filter cap. Since you had also wired around the ignition switch, this eliminated that possibility. What this appears to leave is the white wire. If the white wire has the insulation burnt off somewhere and you left either end hooked up to either the fuel pump or the lower right lug of the fuse block when you did your 12 gauge wire bypass test, then the white wire was NOT eliminated as the possible cause of your problem. It will short the fuel pump voltage to ground from either end and cause the pump to stop working. Perhaps you did have the wire disconnected at both ends when you did the test from terminal 1 of the fuse block, or perhaps it just didn't fail during that test. .... Let us know what fixes it.
