Check all your ground wires, especially the one to the starter stud bolt.

Could be sjb inside fuse box, common problem fir these mustangs water/ moisture damage

This seems like a bad ground or something in alt to battery wiring. Have seen this with a over charging issue after someone doing a big 3 wiring upgrade and didn't have it done correctly. When car over charges it will go nuts all lights go out while driving everything stops working electronically in car but car would stay running. I'd look at the wiring as starting point.

Same, started off cranking slow and not enough to start, checked the starter it's fine, checked the starter relay, it's good, checked ignition, good, battery, good, grounds, good, starter solenoid, good, now it doesn't even turn slow, just clicks. And I don't think it's the solenoid clicking either.

Car went from cranking to when I go to get in it I turn the key it just clicks

I have the same issue was anyone able to find a fix?
Katstang from United States a year ago
Not for me I have no clue what's going on with mine still. But I have recently noticed that somebody had removed the buttons for the cruise control. Don't know if that could have anything to do with my problem or not, it shouldn't, but maybe.
Leif from United States a year ago
I dont think mine has cruise control. I bought it a few months ago and it started fine. Then I pulled the engine and transmission to install a new transmission and when i put it back together it just clicks. Usually that points to a starter not getting enough power but if that was the issue then I think it would start if it has jumper cables hooked up to a running car but it still just clicks
Leif from United States a year ago
PS it has a brand new starter and brand new battery and all grounds are hooked up

Car will not start

Ford Mustang 2003 GT/4.6l 12576 miles
I was driving and all day and i cut vehicle off and when i went to start the vehicle it act like it was going to start it was like a quick vrrgh then went quiet my car is a stick manual transmission so i pop the clutch and the car started. So i figured it was the starter so i went out and purchased a new starter and put it on, and when i went to go start it same thing nothing and yes i put the starter on correctly. I check all fuses and there all good now i can't tell if relay is good or bad because the relay is all black. When I put the key in and turn the key all the lights on the dash come and everything but at that last turn i get nothing ,so I'm asking what could it be.

Ignition switch,neutral safety switch on trans or easiest is to check all the grounds.
Bunky from United States 3 years ago
It is the clutch switch, when u push it in, does not fully put down the safety switch, I taped two pennies on the back of mine with black tape and it has never had that issue again
1FSTSHELBY from United States 3 years ago
Or you could reset the switch all the way back out and works perfectly again.

My fuse box is under the steering wheel in cab

Ford Mustang 2001 Convertable 180000 miles
A fuse fell out and I'm wondering if that is to the fuel pump because cutting out and dieing was an issue but now it won't start at all. I can't find which fuse is fuel pump because you don't have the correct box on your diagram. Mine is under steering wheel not on passengers side

Turn the key and it won't turn over ( changed battery )

Ford Mustang 2006 4.0 186000 miles
I pulled the old battery off for about 5 day's. Replaced with a newer one, and my issue is it won't turn over ,When I turn the key on all the lights on dash is on including theft light I checked connections and tested relays and checked every fuse. Still won't crank. In leaning towards anti-theft or safety switch in the shifter. Any in put would be a great help. It's a 2006 v6 mustang.

I have a 2014 3.7 v6

Same issue with 6000plus I changed starter relays and fuses. Associated. Im trying the diode to pump fuse needed to order one from ford parts counter. 4 bucks for the fuse if this dont work idk. It seems like this issue isnt easy or straight forward thing. Ford said it could be, 1. Pcm 2. Wiring 3. Bad battery 4. Starter relay 5. Blown fuses 6. Starter motor 7. Transmission 8. ABS module. That's a lot of could be problems. They were so excited when I asked the cost of all those items if they were to do them with labor its ridiculous. I spent money on issues they said and im already close to a grand.

Ok you checked all the fuses and relays under hood and in passenger side compartment you said cause there is a 5 amp fuse in passenger kick panel fuse box that is directly for PATS and have had them blow before but if all is good with fuses you have a problem with PATs system itself so need to verify each systems check to make sure it's passing all systems check, before you get to far into trying to read all of the system check check the big ABS plug that's under the air filter drivers side front under hood. I had bad ABS pump and had same issue as you are having ran the PAT's system check and I checked everything tracked it back to ABS block and unplugged the main harness to the ABS and it was full of brake fluid and was making connection with the fluid over all the pins. Cleaned it out and sprayed with electric parts cleaner and fired right up

When I pressed the starter button the entire entertainment system and LED system cut off but the engine was still going. So I pressed the clutch pedal and made sure it was in neutral and pressed the ignition button again and the entertainment system/ LED system came back. I tried to cut it off about 4/5 times repeating the steps cutting it off and on but th… Read complete
