1990 Ford Mustang Power Drain

Most likely some circuit is powerd up with key off. Try disconnect batt overnight if this helps. Then you need a battery drain test done to find circuit and repair.

When I took it to have a power test it shut my car down and now it wont start. I have no power to my fuel pump or power windows. But my lights work and CD player. But it wont start. So I replaced the starter relay and checked my fuses. Still nothing

What was power test? It died during test? There are fuse links on your car looks like wire. Near starter relay use test light find A Brown link it may have been blown. It is for fuel pump. Then check fuse # 14 for power windows.

I checked all my fuses. But I will check the fuse links. But I tried to start my car again and when I put the key in and turned it I had no power. Not to my gauges fuel pump, nothing. So when I tried to turn it over it didn't start but I tried to turn my it over with out pressing the clutch and my fuel pump kicked on. So I'm confused But it still didnt start

So now the car starts, it was my ignition. But I still have no volts. Again new battery and alternator. Every time I put in a new battery and alternator I will drive it and it will show like 11 volts on my gauge then the alternator will fry. Something is shorting out or something is busted somewhere. I just dont know were. Please help
