What happens if you leave the ignition key to the on position, right before it starts the car for more than 10 minutes (besides killing the battery?)

 

Nothing I would think I've had it in that pos while cleaning the car for longer than that before, listng to music

 

So you have had it in the position where the guages are on?

 

Thats all it will do is run the battery down. Why do you ask?

 

when u leave ur door open you will be annoyed to death. and ur battery will run down too.

but like Ntimid8r7 said why do u ask?

 

yea put it on acc and don't worry about it

 

If your car was stone cold your could ruin the oxygen sensors if you started
it before you let them cool down. I guess the mosture in the exhaust
hitting a hot sensor kills them.

 

I think he's asking along the lines of whether the fuel pump is running or coils are heating up, that kind of thing. Basically, what are the differences between ACC and ON in terms of what's running.

 

It won't run the battery down entirely, i haven't tried it but im pretty sure the computer has a cutoff where it shuts everything off if the battery gets too low. At least that's what my mom's 01 Gran Prix did, i figure they're kinda similar.

Did I miss something here? WTF are you talking about? lol

 

Yeah, curious if the coils would heat up and burn out if left on too long. I guess from what I hearing, no one really is sure. Thanks for the input.

 

O2 sensors have heaters to help get them up to operating temp faster. Ive never heard this though, and I leave cars on for extended periods of time for diagnostics on a regular basis.

 

Thats why I asked because I have never heard of that either.
