Any and all imput is greatly appreciated.
My 04 G 35 coupe will not start all the time. Dealership has informed me that all electrical systems are 100%. Battery has full charge and the alternator is working without issues. So what could it be. My car has a manual transmission, so I was thinking it has something to do with the cluth sensor or something having to do with that.
Any other ideas? Thoughts?

PLEASE HELP!

 

what are the symptoms? no crank, slow crank? cranks but wont turn over?

 

When I turn the key, I get nothing...no crank, nothing...it just dies. If I turn the key half way, I can get power to the dash and radio, but when I try to start the car...there is just silence.

 

starter,ignition switch,loose battery cable,bad ground,could be many things.

 

I would definitely check the clutch switch as the OP thought. There's an adjustment that could be off (little momentary on switch down by the pedal) or the switch could be bad. Next time it doesn't work try pumping the clutch a few times to see if you can get the switch to work. Make sure there's nothing in the way of the clutch (floor mat getting in the way). Have you made the clutch mod that raises the final depressed distance?

 

No clutch mods.....The dealership has now had the car for 8 days.
They have informed me that all electrical, battery, starter, alternator are all working fine.
I did ask about the cluth switch....they said it was fine. ( I do not believe them).
I picked up the car and I got the same no start after leaving the dealership!! I pumped the clutch and that worked!!!
THANK YOU! I am having them replace the clutch switch and the car is now having a full diagnostic test.
Thank you Curt G.

 

yikes...
