I turned my car off in a parking lot and tried to start it up immediatley after but it wouldnt even crank.
Towed it to my house and began work on it.
-Checked battery and starter both are fine.
-Checked to see if power was getting to the starter from the battery and it is.
-Replaced ignition switch. (brand new part)
-Tried to reset the VATS system (Process didnt work)
-Wiring harness to the BCM has 3 splice points that didnt lead anywhere, The yellow, pink and red wires had been spliced on the old ignition switch.
After all of this work The car still doesnt start and wont crank at all. The lights and everything work when I try to start the car (Headlights dim when i try to start it). The key is a non origional key with no transponder (Axxess+ 14R2). Does anyone have any ideas?
