Hello Scotty big fan of you
I recently bought a 2008 pontiac g5 manual transmission because of my budget... For 3 months worked very good until 1 day in a stoplight it died and I couldn't start tge car again, no crank no check engine light , dash started to say power steering, and service bag... I push the car into a hill and tried to start the car with the gear ... Nothing I parked the car and before calling the tow truck tried again amd the car started like nothing ... I went home put a OBDII scanner ... No codes no dash lights nothing... After 3 days driving normal I went to a gas station after putting gas... Car wouldn't start dash saying "service air bag" no flashing just solid on... No crank.. I tried. Too many times with no luck I unplug the battery for like 5 minutes tried again , same results and when I was giving up tried again ...started right away ... It looks like I have to wait for like 10 minutes in order to be able to start the car. Cuz after starting the car from the gas station I went home I turned the car off and back on to check if it was working and it did the same thing no crank and after a few minutes trying started again same message on dash device airbag.. I checked under the pass.. And driver side for possible harness damage or problems with the connections, I didn't see anything wrong... Thanks so much Scotty I hope you understand I you can help me
well you obviously have some type of strange electrical problem knowing those cars that could often be the main computer or the wiring harness that feeds it is either shorting out or when you remove the giant wiring connector from the computer you might see green corrosion showing that the computer wiring is corroded and since they only have milliamps of power any corrosion will keep them from working correctly at odd times because of lack of tiny amounts of electricity

Thanks a lot for your answer, I found a video about a temporary fix putting a ground wire from the TCM to the body of the car..... I couldn't find the TCM of my car so I did it on the ECM and it worked when it died again... I wonder for how long it's gonna work ... And does a manual transmission do not require a TCM or did the last owner removed it..? I saw some videos that the TCM it's next to the ECM.... My car has an empty slot where the TCM suppose to be ..or since its a manual transmission it's located in a different place...
