Flashing SES
Trans am 350 Tpi -91
I have a very strange problem.
When I turn on the ignition my ses lamp begins to flash every 2-3 seconds. At the same time my primary cooling fan goes on and off.
The air select and air divert thing clicks like its gone mad. When this happens i cant start the engine.
I have checked and sprayed every sensor and relay connections I can find and they all look ok. The only code I can pull from the ecm is 12.
If I leave the ignition on for a few minutes everything goes back to normal and I can start the engine.The car runs perfectly with no ses lamp untill the next time I start it.
