No spark, no injector pulse. Help needed No spark or fuel injector firing. I have power to both coil pack harness and injectors but i don't have ground?
Bone stock Gen 3 4.8. Stock swap harness, stock computer with basic stuff done just to get it running.
I have the harness ground on the back of the passenger side head which is also connected with a ground wire running directly from the negative side post on the battery.
I have a ground wire for the harnesses fuse block hooked up to the rear of the passenger head.
Then i have a ground cable on the block to the core support.
I was getting ground at the coil pack harness the very first time i hooked up the harness to the computer but that was the only time.
What do i need to do?

So i believe i got my Cam sensor, MAP sensor, and Crank sensor plugs mixed up. The swap harness didn't come with instructions stating which go where.
Can someone tell me which connector is which by the pigtails wire colors?
I didn't get a pic of the crank sensor plug i have but i have these 2, and out of these 2 i don't have anywhere to plug in one if i plug in one of them. Either one if not plugged in, doesn't have somewhere to plug in.
