02 Monte Carlo won't start
Permalink Closed


Ok, so I go to start my Monte Carlo one day But when I turned the key, nothing. But the battery signal thing was on steady, so I think, dead battery. But you won't be able to use the radio or horn right? My battery and security lights come on when i put it on accessory and all my windows and lights work. My locks won't but everything else does. So if that is not it I am thinking, bad starter? I've replaced the starter twice now and even the battery and it still won't even try to turn over. After i replaced the starter we tried jumping it off the solenoid and it started and then died multiple times. It makes a clicking noise but I have to listen really hard. I don't know what else to do!

sounds like it's the ignition switch.

pretty common issue with these and is available at any auto parts store or dealer.

Ignition switch, passlock or BCM. Those are my guesses.

Seen the same symptoms before and seen different causes, all of them are listed above.

Jumping at the solenoid bypasses the electronics and the car wont stay running. Even if everything was in perfect working order.

Ignition switch - each part of the switch controls a different function, OFF, RUN. START, ACC. If the START portion is corroded or not making good contact, it wont start but other functions may work.

Passlock - similar to the ign switch where car wont start but other things may function.

BCM - If the BCM is fried, it wont relay the VIN to the PCM and the car wont start. (just one of the many symptoms a fried BCM can exhibit)

I would try some contact cleaner with the ign switch before throwing more cash at it. The switch can also be tested. Id start with a continuity test for all functions. Beyond that, I cant help any.

We're pretty sure it's the bcm because my dome lights don't work when it does it and neither do my door locks but it only shuts down everyonce and a while it started at 10 yesterday morning and we i got there at 12 it wouldn't and it started again this morning as well

when you turn the key, does the check engine light go on & security light flash?
If it does its the bullsh** passlock system. The only way I got out of being stuck from it was wiggle the key in the ignition till it kicks & use the fob to lock & unlock to doors.

Yes that's exactly what it does it flashes between the battery and security. I don't have keyless entry so is that still possible??

Then its just the chip in the key, the passlock system isn't recognizing it. Whenever it gets me stuck I usually insert the key and remove it a couple of times, & turn the key all the way to the 'start' and jiggle it a bit.
I've been told you need to go to a qualified GM mechanic, they need certian tools to read the passlock system. Usually once I get it to start the security light doesn't come on for a while...but when it frequently comes on I usually will get stuck within 4-6 startups.  If yours has the same thing, then atleast its a good idea when your going to get stuck again.

Try unlocking & locking the doors with the key and with the inside buttons, or just do the above till you start. 

If you want to give this a shot to bypass the problem, go ahead:

I don't think so, its something that usually happens over time. I've been told it has a chip in it & some say not....or its just a bad connection to the ignition cylinder. When I took the car back to the dealership they said their scanner said there was a short in the cylinder. Unfortunately they were a ford dealer, & didn't have the tools to reset or fix the problem ):

& now the warranty is up so I'm stuck with it.
