Default Reasons why ECM wont send start voltage to relay.

Fixing a flood dammaged car. New BCM/ECM/VCIM, Questionable Contacts have been cleaned or replaced. When turning the key, the relay on the BCM relay clicks, but no cranking.


Just shooting for ideas, only thing I can think of off the top of my head is maybe a bad clutch switch, which i'm going to check tomorrow.


Most things are working correctly in the car as of right now, lights, gauges, etc etc. Just not cranking, and when I say not cranking its not the starter. The ECM is not sending the signal to the relay.

It's a solstice, but the start circuit is very similar to a C6 corvette.


I just asked here because not much aftermarket stuff going on with solstices, compared to ls1tech.

Neutral safety switch has to be closed to activate the relay.
