No, the starter will not fit. Different engine sizes and different starter styles.
why would my starter wire burn, going from starter to battery
No. A bad starter would cause the car not to start.
I would suspect a defective ignition switch. I would be more inclined to believe it was the starter relay/solenoid thingy i used to have an old amc eagle. and it did same thing starter wouldn't disengage. I replaced the solenoid/starter relay and it worked fine after that.
You need to replace the starter.
It would if the battery voltage was lowered enough to cause it not to fire.
The starter itself.. that would be unlikely... but a wire connected to the starter could on some vehicles.
The starter is probably not aligned with the flywheel. The clearance between the starter and the ring gear needs to be checked.
The starter relay (solenoid) points are melted together.
Starter selenoid no good
bad starter or starter solenoid.
what would transmission not to shift in to overdrive
