Camaro was running perfect until I left my headlights on overnight. I removed and recharged the battery but now the check engine light stays on and won't go off. Car is running rough and won't idle.I am thinking that no power is going to the air fuel solenoid at the carburetor.Keep in mind the car was running,shifting and timing was advancing properly until headlights were left on and completely drained the battery.Please help!

 

Have you checked the codes yet?

 

Doesn't flash any codes and not sure how to check them. Scan tool that I bought from part store doesn't pull up anything.Only had this car for couple of weeks so really want to get this solved. Any help is appreciated

 

isnt ther a fuse link or inline connector on these that comes off pos cable and powers ecm? possily unplugged or damaged when battery was removed?

The ECM power is a wire connected to the positive battery cable, runs along the frame rail under the radiator overflow tank. Check out the connection there.

 

That was the problem...Thanks for the help
