Hi I'm new to this forum and I really need help I just got a 2005 monte carlo ls and it was working fine up to 4 days ago I got the car in florida and drove it back home to colorado it was starting fine and the last 4 days it won't crank or start in the morning but when I get off of work it starts right up I think it might be the security system but I can't deactivate it because it doesn't have the stock stereo in or is it the starter any ideas on what I can do thank you

 

What kind of motor do you have in it?

 

3.4 v6

 

Is the security light flashing 3 times? Or is it just solid?

If it is flashing 3 times, you're probably dealing with the ignition switch failure. Not too hard to fix, but it's not cheap. Just take the dash off, remove 2 bolts, pull the ignition cylinder out, unplug it. Then you just plug the new one in, reassemble it all, and do the security relearn.

 

I will take a look this weekend and see and I'll get back with you

 

So I looked at it the security light is solid and I tried starting it at nigh without it running all day and it's doing the same thing

 

I'd say take a look at the starter then.

 

I will and I am going to check the relay switches to see if the contacts on the pins are making a full connection
