Hi!!

You may have the positive cable hooked in the wrong side of the starting selenoid or the starter selenoid is defective.

Follow the RED (+) cable from the battery, it goes to the starter selenoid wich has two terminals, change the cable to the other terminal, that should take care of the problem unless the selenoid is stuck on. Replacement runs about $15.

Manual for a 1993 ford mustang relay switch for cooling fan


I'm not sure but I think it is in the engine compartment. Follow the wires coming from the fan going to the relay switch. One wire is a ground and the other is power. If you have air conditioning there could be three wires for a two speed fan. Good luck.
