Check the starter cylinoid...it is mounted on the wheelwell and in essence is the relay to activate the starter

FYI, getting 12 volts from car battery using a volt meter means absolutely nothing. A car battery must put out AMPS, and a lot of them, to turn over an engine. A battery can be almost completely fried with only one working cell, and it will still put out 12 volts.

As I always say, if there's any question about a battery, take it to Auto Zone. They'll charge it overnight and put it on a Bear battery tester. That's a very good tester and it will immediately reveal any issues.

Unfortunately, you're not going to be able to diagnose dead cells, or any other issues, at home. And the first step when diagnosing a starting system is to verify the battery is good.

Search function is your friend- but clicking is classic mustang speak for a bad connection, a solenoid, or starter. In my personal experience the probability follows that order. Fast way to tell, short out the solenoid- if it starts- theres your prob, if not, clean up the connections on the solenoid, starter, and engine block (you can measure voltage at each one if you wanna see where the prob is/was) If this ain't it its time to r/r the starter

Klutch is right, voltage is only half a battery test. I use a load tester when in doubt. Try jumping it from another car to eliminate or confirm the battery.

ok cool, i thought about the solenoid after i posted the question. I jumped it with a stand alone jumper and it started then but wont start again. The battery looks like it has seen better days so i think its a bad battery, ill take it to a place soon to have it tested.
