Car won't start at times

An engine needs three things to run : Fuel, Compression and Fire. Check to make sure you are getting fire to the spark plugs. The fuel pressure regulator on the injector rail may be bad. There is a schrader valve on the injector rail, check to see if there is fuel there. It is a valve like a tire valve, depress it slightly to see if there is fuel there.

Check the battery terminals. If they have become corroded you could be getting a bad connection. When the starter is engaged it creates such a power load at the connections that it will arc and loose power. Or, you could have a bad ground wire off the battery. Also check the positive cable leading down to the starter. Most of the mustangs had the battery cable leading to the starter between the engine and the exhaust manifold. Eventually they melt through and can cause a short. This would require replacing the cable. Good luck.

If your starter is turning but not turning the engine over then the "bendix drive" in the starter needs to be replaced. This requires disassembly of the starter once it is off the truck. Usually the best bet is to replace the starter unless it is new in which case the bendix is probably defective.
It's a remote possibility that there may be damage to your ring gear on the flywheel, but that can be checked when you have the starter off the truck. Just look at the teeth in the starter hole and make sure none are missing or chipped or narrower than the rest. They probably are but it doesn't hurt to check. Hope this helps.

Check the starter and the starter relay or fuse. A client of mines car was doing the same thing, it ended up being two issues, the starter not working anymore, and a relay that was bad. If I am not mistaken everything should be labeled in the fuse box under the hood and will tell you where the fuse/ relay is for your vehicle

After you kill it, when you try to start it back up, does the starter turn the motor? Or is it froze up (will not turn over)?
