Any 2011+ mustang experts around? Mine won't start, checked keys, battery fuel, no turnover on key to ignition, checked relays on starter and changed them with neighbors, reflashing ECU, checked connector on clutch NSS and manually pressed it. No DTCs, no warning. Just seems like no power to starter. About to roll it back and jack it up for inspection of starter power.


Car has good fuel, 13.2V on battery, and no other odd behaviour.

 

Do you have any power with the key in the on position.....radio, windows, heater.......

Check all the ground connections under the hood. Could have corrosion.

 

try holding gas pedal down and starting

 

Why do you have to go through all that trouble, isn't your car still under warranty ! Have it towed to your dealership.

 

Is the PCV valve (the piece many replace with a JLT oil separator) fully latched on? 'No power to starter'....Doubt it, but a fuse?

 

This is kind of awkward. May seem like the cheap way out but before I'd start messing with things and getting more Involved, I second just getting It to the dealer.

 

Try moving the tilt steering column up and down then try it. We had a 2011 expedition in for a service that did the same thing. Started when it came in, but did not want to when leaving. Played around with the tilt, and off she went.

 

this, try turning the wheel while starting, the steering wheel may have locked up

 

push the clutch in

 

Ring Ring...Hi ford dealership my zillion dollar mustang under warranty won't start...get out here with a tow truck and loaner car...and maybe bring me a warm coffee also...done...click.

 

Ring Ring...Hi Mustang owner, this is ford dealership returning your call, you've added an intake, CAI, tune, etc. that voids your warranty, its your problem now....done....click.

 

I was thinking the same thing...........

 

I must add........Move around the steeringwheel, like others have said. I think its called a 'clock spring', (something like that) could be going bad.

 

If it won't turn over I'd look at the switch on the clutch pedal.

 

Eventually it started again.

So the situation was/is this:

-Key on power was good
-Accessories would run
-you could hear the starter relay trigger when key pushed to start
-No noise or movement from starter
-I did not look for theft light, play with clock spring, or otherwise (did try both keys)
-Eventually on one start attempt at the very end the starter began to move
-Next start attempt and every one since the car starts normally

Either loose wire, or something's overheating, I'd think. It is going to the dealer, but I wasn't in a position to get it to a dealer when it left me stuck at a gas station.

 

Have you wired anything up recently?

Looking at your mods, nothing listed could really contribute to a wiring issue...

Are you running a shift light? Additional lighting? Stereo equipment? Anything that you may have tapped into your ignition for power?

Never heard of any starter issues with these, but that really doesn't mean anything.

Did you have any signs of this during the summer months?

No long tubes right?

 

nothing touching ignition circuits, factory exhaust (through midpipe, despite being a boss midpipe, its factory ford parts).

I'm thinking maybe a loose connection on the starter, given how many other items have been lazily serviced or left loose on my car by the local quality ford dealers.

 

If you have a power converter plugged into one of the power supply outlets that allows plugging in regular electrical plugs that has been left on, it will drain your battery. Happened to me with my 2008 Mustang.

 

might just be a low battery..
testing it with a volt meter and it shows 12.6v just mean it has 12.6 volts.. but if it doesnt have any current it wont start the car i would load test the battery.. but you can still use the radio.. esp. if you heard a click when turning to the start position and nothing happend.. or it can be a loose + battery cable that is grounding out, which has happened it it will do the exact same thing as your describing..

 

I've had the exact same thing happen in both my 05 and 2011. Completely random, just a click when you turn the key. Mine eventually started, I never investigated it but I thought it could have something to do with some electrical interference with anti-theft chip in the key fob...?
