Car won't turn over.
 

Okay, so I have a 02 z28 (m6) and when the car sits in the sun for a long while, I'll unlock the door with my key, the alarm will start to go off, and the car won't start.. I'm thinking it could be something with my starter because the car won't even turn over. But why would this only happen when the car sits in the sun? Any suggestions would be greatly appreciated..

Your alarm is still engaged it won't let you start the car mine does it as well some time y I have no idea

If this is the stock alarm, you have to put the key in the ignition to turn the alarm off. Do you have VATS disabled or anything like that? Is this a stock alarm?

I have stock alarm and sometime wen I put key in ignition it still goes off

Yeah it's the factory alarm, and vats is still on. I've been wanting to take it off, but I just haven't had time to do it yet. And even if I put the key in my ignition the alarm will continue to go off

Does it take a while for your car to start up again?

Are you turning the key our just putting it in? I recall that maybe you have to turn it at least one click?

If the alarm still goes off when you turn the key, it sounds like something in the BCM isn't working to deactivate the alarm on the key turn event.

Yup sometimes, sometimes I just disconnect the battery and wait a few mins and it's fine

yes I turn it to the on position

Anyone else?? I'm still having this issue, and its getting pretty annoying..

Okay so I've been reading around on the forum and I've come to the conclusion that it is most likely vats that's doing it, so I'm gonna get my buddy to take it off with hp tuners today, and I'll post up the results later...
