So I have found that if I carry both keys with me and I have a no start/no crack concern I charge the key I am using car starts up. This no start takes place more often when the weather is hot. Does the integrated power supply module supply power to the ingition curcuit? I have tried to find wiring diagram on the ISM but have had not luck.
I have also found that if I disconnect the power connector at the right side next to the jumper post I can get the car to start 50% or the time. Other times I have to have it disconnected for about 3 minutes and then start the car.
When I checked for faults with buddy's GT1 we found many historyical battery faults.
