So I got back from the car show on Saturday and turned the car off to unload the trunk, etc. Went to start it up and pull it into the garage, and all of a sudden the starter will not rotate the engine. All I hear when turning the key is a loud "click" as the starter engages the flexplate.
I tried to jump it with the other car; no change. The battery reads 12.5 V with my multimeter. The engine is NOT seized; I can turn it over with a breaker bar and it does not seem to have any more resistance than normal
I assumed it was the starter, so I took it to autozone and had it tested; it passed. They gave me a new starter under warranty anyway, and the new starter does the same thing.
I had an assisstant turn the engine over with a breaker bar while I felt the teeth on the flywheel, and they feel normal.
I also bridged the solenoid with a screwdriver to see if that would crank the starter and it does not; again, it (the starter) just clicks loudly as it engages the flywheel.
At this point, I am wondering if it could be something electrical? Is it possible that an electrical problem could cause the solenoid to engage, but the starter motor not to turn?
