Mustang won't start all of a sudden, battery good

10

Asked by May 12, 2016 at 02:50 PM about the 2006 Ford Mustang V6 Premium

Question type: Maintenance & Repair

Tried to start my 2006 Mustang the other day, and the gauges acted kinda
funny and the CD player made sounds like it was switching CDs.  Radio came
on as well. Weird electrical stuff.  Turned key to start position and all I got was
the fast clicking noise like the starter didn't have enough power to engage.  
The windows still worked and everything seemed fine but the gauges still were
funny.  
Checked the battery and it was at 11.3 V.  Cleaned the terminals and put a
charger on it.  Got it up close to 13 V and went to try it again.  This time,
nothing whatsoever. Radio and dash lights didn't light up and power windows
wouldn't work. However, headlights, dome lights, and power seat worked
perfectly fine.
Had the battery load tested at Advanced Auto, passed with flying colors.
The car had sat on grass for 3 days prior without running, which is the only
thing that was different than normal for it.  Even this past December it sat in a
parking garage for a month but started right up afterwards.  Never ever had
any starting issues.  Other than that I drive it every day.  A little over a week
ago I drove it on a 700 mile 12 hour trip, and that's the only thing I think could
possibly cause anything.
The car has 35,000 miles on it and has never seen a winter.  Help!!

Sounds like some electrical problem! But the mustang I owned several years ago had the same problems. After putting a new starter an alternator and battery in it the it still would not start. I done some research on it an found out that the key was bad because in had a computer chip in it. I bought a new key for it an it started right up with no problems. Just my advice on the mustang I owned. Also check your fuses.

How old is the battery? being at 11.3V concerns me, maybe a draw?

The battery looks fairly new, I only bought the car last summer so I don't know the battery's exact age. It passed the load test though and has held charge. And with the key thing, I have a spare with a chip which I tried, and got the same result. I checked a few fuses, but not all of them. Should I check all the fuses and relays associated with the ignition circuit? Also, side note, is there any way I can directly connect the battery to the power windows so I can roll them up? Car is stuck outside and it's going to rain soon

Has a BAD ground check all connections MAIN grounds under hood. Needs a voltage drop test preformed on the starter circuit 10 minutes with a multimeter. Then after its running check the Alternator output 13.2 - 14.8 volts

Did you ever figure it out. I have a 06 4.0 doing the exact same thing.

I have a 2011 that I just figured out. It was the starter relay in fuse box under the hood. $11.22 and could have saved myself a battery and starter.
