Ben, is the battery for this vehicle in the trunk or under hood ? If in the trunk how is it grounded ? If it's in the trunk and grounded somewhere in the trunk area do you have a dedicated ground wire to the front of vehicle? Also you stated that you "hard wired" an HEI unit direct to the battery with the same results which would nearly eliminate the switch as being the issue as you have bypassed it alltogether, we still have the question of sufficent voltage. From rereading your posts I'm starting to believe you have a mechanical problem assuming your voltage is sufficent to operate the vehicle. Have you performed any mechanical diagnostics, compression test, leak down, checked spring pressures, checked valve action while rotating engine with valve cover off? just some thoughts. Joe
