Chevy won't start key turns all lights come on security, battery, abs, brake, check engine light & Traction control lights.
I have replaced the battery, checked all fuses, relays and coil, starter. The anti theft locks Don't work. My chime & Audio system goes in & out. My automatic door locks Don't work aren't getting power.
I also made a new key & relearn ed the pcm.
Checked the neutral safety switch.
Besides the recall for ignition & Reprogramming of the BCM. What do I need to do? It starts one day no problems then a week later won't start for 2days?; (
Thanks,

 

Replace the BCM - This happened to my 2001 Impala and the dealer told me that many BCM's were found to have bad solder joints on the circuit board causing numerous intermittent issues.
