IIRC, that goes to your EGR which looks to have been deleted on your car

Between the starter and block. That plug is definately the a/c compressor plug, it would not have anything to do with a no-start. Check the ground on the back of the heads, and the ground on the radiator core support.

Yep forgot to plug in the cranck sensor. I am getting spark now but the car acks like it wants to start for a second, i little pop, the i pull the plugs out and they have fuel on them. I take them out and clean them and same thing. Could this be VATS? cutting my Ignition? I dont know what else it could be.

Shortest answer i could find from someone other than myself 
Like i said too much current, ie almost like a short.
"Why can't I run low-impedance injectors with the factory ECU?
Virtually all cars come with high-impedance injectors. The ECU turns high impedance injectors on and off with a simple switch, much like an ordinary light switch. Turn the switch on when you want fuel, turn it off when you don't.
But you can't run low-impedance injectors that way or you will burn them out! These injectors need to be carefully controlled, so a simple on/off switch will not work. They need something more like a dimmer switch. Turn them on all the way to get them to open, then after they open, turn down the dimmer so they don't get too hot.
The second problem is that the ECU's injector drivers can't handle the large electric current needed for low-impedance injectors. Low impedance injectors need about 4 times as much current as high-impedance injectors. This much current will burn out the transistors in the ECU that run the injectors, unless the injectors burn out first"

I'm not saying your wrong at all, I'm just trying to understand how a ground pulse to a different type of injector could damage the ecu. I totaly understand how it could fry the inlector.
