Hey everyone, I have a question for anyone who can give me any input. I have a 99 Mustang GT (Standard if it's relivent), and i've never had to take it to the shop since i bought it (knock on wood) a couple days ago i stopped at a store and when i came back out it wouldn't start. Turns over but won't fire up. Tried jumping it to no effect. Was about to push start it with some friendly helpers when it started on it's own about 30 minutes after i first tried to start it and failed. Now just today the same thing happened when i stopped to get food. Wouldn't start and after i waited about 15 minutes, fires up without a problem. Some people swear it's the alternater, some swear it's the starter....Any input on which it is? I like to take care of her myself so i'd like to figure it out before i have a mechanic look it her. Thanks!

I doubt its either, but try cooling the starter motor after it wont start, just use a spray bottle of water and wet it down a little bit, if that doesnt work then assume starter is ok, alternator only charges the battery it has nothing to do with startup, it only comes into effect when the car is running.

A bad ignition module will cause this to happen.Had a eb falcon that did the same thing,its would start and run for a few k's then stop,and only start after about 15-20mins.It was the ignition module heating up and stoping the engine.
New module,no probs after that.
That may be the problem.
