Default starter comes on while car is already running!!!

I am having a problem with a 2006 c6. The starter will start running while the car is already started and running while I am driving down the street. You can shut the car off but it continues to keep trying to start it and the only way I can get the starter to quit turning the engine over is to unhook the battery. Whenever you try to hook the battery back up it immediately tries to start again. Now when it is trying to start itself up it does not actually start the engine, it just turns the engine over until I again un hook the battery.

I took the starter off and the positive post on the starter solenoid is melted pretty good and the post is very loose. I am thinking this is the problem and i will be buying a new starter on monday but I was just curious if anyone else has ever had this problem.

Had the same thing happen on my Chevy truck one time. It was the starter solenoid...

Sounds like it's just the solenoid.

I would have assumed that was an electrical issue since the soleniod needs voltage to engage. If it isnt an electrical problem, is the solenoid just not mechanically disengaging?

The solenoid has twelve volts at the terminal 100% of the time. If it is defective I'm sure it could be the problem. There is one way to find out and that's to replace it. There cheap and easy to replace.



The large cable on the bottom is the the other end of the positive battery cable.

There is a contact inside the solenoid looks like a thick copper washer and over time they get dirty due to arcing and can stick which keeps electrical power applied even in the run position. The old solenoids you could remove from the starter and take the copper washer out & sand it clean & reinstall. Don't know if that is the case with the ones in the Vette, but the OP's symptoms suggest a stuck solenoid.
