Need help with a Gen 5 no start condition
Very long story short, transmission died last April. Finally got it back yesterday. New trans, Circle D converter, Powermaster 9004 starter, AC Delco alternator and Lingenfelter launch control. Started at the tuner's and drove home, no issues. Parked in the drive and shut it off. Went to move it into the garage and upon the key turn all dash lights except for the CEL and seatbelt went out as well as the My Link screen. I did a battery disconnect that didn't help. I had OnStar do a diagnostic check. No codes. Thoughts?

What is your battery voltage?
Could it be the alternator is bad or not connected properly?

#1 reason is usually Battery, Battery, Battery.
12.5 V with car not started, ~14.5 V running. If not more than ~12.5 V running then it is not charging. Other issues are poor grounds, Throttle sensor connections, etc. Since you got new "Powermaster 9004 starter, and AC Delco alternator", best to check installed connections of these. I would imagine there is a code or 2 thrown which would pinpoint the culprit, get a code reader to find out to eliminate the guesswork. |

The battery is fine. Tuner thinks the starter may have a loose connection on something called the "fire trigger". He's supposed to be coming by the house to have a look.
