Well the vehicle isn't a mustang, its an 87 chevy truck. But I know this old trick goes for pretty much any vehicle out there. And this sub forum does say "non mustang related". The truck won't start, it won't even try to turn over. Sometimes. Anyway, you can get under there and tap on the starter a couple times with a hammer, and it will fire right up. What does that mean? I'm trying to avoid just throwing parts at it, until I finally get the right part. Is that an indicator that its the solenoid? Or could it still be something else?
