I screwed up big time....

I'd start checking if voltage arrives at the fuel pump with/without the killswitch (or just have someone listen: contact on and kill switch on/off and you can hear the fuelpump working for a second when you swith to "on").

I wouldn't be surprised if there is extra protecction not to allow a melting wire inside the fuel tank, so I'd check that circuit first.

The harness shouldn't be the weakest point on any installation: no matter what you connect it to. Fuses (or some components acting as fuses) are there to prevent wires to get too hot and avoid fires. So I don't think you'll find a melted wire. But I've been wrong before...

The noise is there even when the tank is removed- so something else 'primes' when the key is turned- I just don't know what. You hear the relay click- and something goes bbrrrrrr for a couple seconds.

I saw smoke and heard sizzling around the battery area- but opened both the power commander and the autotune box and saw no visible damage or sign of heat.

Fuses are typically on + wires- to prevent over current. Reverse polarity is different- sending power in places it was never intended to go.


I'll check the 12v to injector when I get home from work this afternoon.
