I have a 2005 Z51 M6 and well she won't start. I checked the fuses under the hood and under the passenger footwell, everything checks out ok. I have a feeling it may be the clutch depression sensor that the clutch pedal pushes against has finally gone out. Does anyone know how to check that and see if it's working? The battery right now is sitting at 11.8 volts as well (and I even tried to jump it just to be sure, and that won't work). Accessory mode and all the electronics in the car come on fine, but she won't start. Not even a hint of trying to turn over.
The battery is only a year and a half old. Wouldn't the car have started even if the battery were bad when I attempted to jump it?
Any other ideas? I'm open to suggestions.
Any headers on the car, if so check your starter, if after that it didn't start, then check at the right side rear fender weld and see if the ground wire is terminated properly.
I believe it could be the starter or the wire around the starter. But, then again, what do I know about cars?
The car is a bone stock 05 that I bought new. I will check in the right wheel well for the grounding wire. I have a set of maintenance manuals and will look in there tomorrow to see if they can be any help as well.
I'm really hoping it's something more simple than the starter, that would be a pain in the a$$ to fix. It seems a bit premature for it to go out so soon.
Not necessarily. I had it happen to a 1 year old battery.
Would it matter if when I tried to jump the car, the voltmeter was showing 13.8 volts (ie running off of my truck's alternator?) Is that any indication if the battery is good or not? So it read 11.8 volts on its own in acc mode and even when I attempted to start, then 13.8 with the jumper cables connected from my truck.

Hmmm.... I'm still baffled.
My battery wouldn't start the car with my 100 amp start charger or my stronger booster pack. The battery was shot.

The starter is very easy to get at and even change if necessary, all you have to do is raise the right side and put a 8" block under the wheel, then crawl under the car and 2 9/16 bolts and the main wire to be disconected and its out. If you have headers then it become a little more difficult but will still come out the same way
I am not saying its your starter, but if the battery checked out good then your next step is the starter.
Does anyone happen to know about the clutch switch that the clutch pedal depresses against?
All the electronics in the car work 4.0 in acc mode or when attempting to crank the car (radio, HUD, nav, headlights, lamps, etc) just no vroom when I push the start button. Is there any way to test and see if it is that particular switch?
I still haven't taken the battery in yet. (been doing valentine's day with the fiance' )
Do starters usually just fail outright, or is there ever warning signs that it is about to go? Contrary to my ramblings here, I'm pretty mechanically handy, I'm just not a particularly good troubleshooter. That's a skill I'm still working on.
The clutch switches do sometimes go bad. My friend Jschillit here on the board had that trouble. I haven't looked at mine, but my guess is you can unhook the connector and put a jumper wire between the two wires (assuming there are two) to simulate the switch being depressed and try starting it.
You might also try unhooking the battery for a while...to let the car "reboot". Sounds silly, but I recall stories of that working to fix problems.

Both of these are free, and pretty easy to try.
Keep us posted.
Joe G, you are a brilliant man!!! I disconnected the battery and let it sit for about 10 minutes. Reconnected it and viola!! She's running right now. Thank you sir for that simple yet ingenious fix. I knew I had to be overthinking it!
Hopefully this is not an indicator of something potentially going bad. Anyone know the life of the clutch position start switch? (that's what the service manual calls it) Again mine is a bone stock 05 with 66k on her. Mine since new.
The starter sounded strong when she started up, no whine or weak sounding turn over.

Wonderful! Best news I've had all day.
The clutch switch should last the life of the car.
After sitting 2 months, things can go wonky. After sitting a couple of weeks recently my car appeared to be dead, no fobs worked, etc. I used the key to open the trunk and the door, and viola, things reset themselves and all was fine.
Even a Mac needs a reboot once in a while, so does your car!
Glad that worked out. I'd stop worrying and enjoy the ride.
Could be your anti-theft deterrent system, too. I had that problem and after the stealership fixed it, it went along with the SAH/STC/SES problems. Just my 2 cents.
