ok so this is really weird, i drive my car to work yesterday, everything was fine. when i goto leave i turn the key and all i hear is "click" (starter trying to turn) and that was it... dead... battery has proper voltage.... tried jumping it... heres the weird thing. when the key is on lock it beeps and its all good... when i turn it to acc "sometimes" it will turn on the fuel pump and fans.... and if it does.. when i turn it to start with the clutch in i get the same click and dead... after this happens if i turn the key back to lock, all the lights in the car are super dim but if i wait about 10 seconds i get proper voltage back.... im getting 2 votls or so when its in this finicky state.... anyone have ANY idea of what the hell this could be? i would think a ground wire but i checked all the ones i can get to. including the main ground(s). do you think maybe its just the ignition switch shorting out?

this is a 6th gen 3sgte swap with many miles and no probs untill now.......
