Try a jump start and see what happens. Maybe your battery has too little power to turn over the starter but just enough to make the lights work.

Same problem : I turn the key and other than the indicator lights coming on, nothing else happens - no clicking, no turning over of engine, nothing. (the battery was verified good).

I also tried jump starting it, and also tried leaving the key in position 2 for a minute
to allow the gasoline to be pumped in - nothing

Any suggestions ?
Thanks

I was thinking it is a brake sensor switch (?) or something related to that because the 'non -start' issue is behaving as if I'm not pressing the brake pedal prior to turning the key.

Can anyone tell me where the switch or sensor is located ? Is it somewhere on the actual brake pedal ? I will look around.

Any other possibilities ?
Thanks very much

Brake switch has nothing to so with engined start.

Do you have an oem alarm? Is it completely disabled? Used to happen to me when I didn't completely disable my alarm.

Great suggestions, i'll try another key.

Regarding the brake switch, isn't that related to having to press the brake to start the car ?
If not, then what sensor tells the car you're stepping on the brake ?

Thanks all.

I will try the starter as you suggest.

But is that still the case for me because as I said, other than the indicator lights coming on, I get nothing related to ignition - no click, no engine turnover.

I do hear something though, I believe someone said it's the hydraulic pumps loading up
in order to be able to shift the gears.

Thank you for your suggestion.... I will keep everyone informed as to the resolution, I
have a mechanic coming over tomorrow with the diagnostic tools.

This is what i've tried so far : another key, jump start, the switch related to changing the gears, the brake switch, battery is ok.

Still, the car won't start, won't even turn over.

When you turn key to position 2 do all your check lights come on as normal if not I would say it your battery

Well, the mechanic/friend came to my house, connected up the diagnostic computer, cleared some error codes and the car is running like normal.

Anyway, thanks all for your suggestions, I did try most of them...

Amazing.

Hey no one is more happy than I that my car works again....
Thing is, I'm a little paranoid now, maybe it'll happen somewhere less convenient
than at my home....

Glad for all of the suggestions though, I'm learning more and more about this car.
Thanks all.

Michael
