Alero 2002 won't start
Alero 2002 won't start
I have an alero 2002. The car worked perfectly until one night I went out to turn the car around due to an upcoming storm. I found it odd cause it took me 3 try to start the car, usually it start on the first turn. The next morning the car wouldn't start. I have check the fuel pump wich seem to be fine cause I got good pressure, I have spark at the plugs. I have change the coil plate above the plugs, I have change the computer behind the glove box and I have change the ignition switch. I have reset the entire thing about 5 times and I can't get rid of the security light and the car won't start. Anybody got any ideas?
Re: Alero 2002 won't start
If you've got a security light staying on, then you probably have an issue with the ignition cylinder, NOT the ignition switch. The Passlock sensor, which is for the theft deterrent system is part of the cylinder housing. If you've just replaced the switch, that doesn't do any good. You might want to get the car scanned for codes, especially Body Control Module codes because that's where any security problems would be stored.
If you do need to replace the ignition cylinder, you will need to do a re-learn procedure to reset the security system.

Thank you for your tips, I taught the ignition cylinder was in the switch. Is the ignition cylinder in the steering column?
Re: Alero 2002 won't start
No, the cylinder is inside the switch, but they are replaceable separately. You need to replace the ignition cylinder and housing (which come as one unit), and then do a theft relearn.
And just so we're sure.....the IGNITION SWITCH is the large black plastic piece with two large connectors that the aluminum IGNITION CYLINDER slides into. You said you replaced the switch, which has nothing to do with the security system.

I got rid of the security light but still no go, I'm about to put an axe in it lol. It's still turning fine and seems to want to go at some point! I put the OBD2 car reader to it and I'm not getting any error code but I have a steady yellow light on and I have the C, O, OH, EV monitor icons flashing

I have a 2001 Oldsmobile Alero and I had the same problem with it not starting. Come to find out it has what is called Passlock on it. This has to do with the security system. Try this when it will not start, Turn the key to the on position leave it for about 10 minutes or until the security light stops blinking. Turn back to off position then start the car without pumping the gas. My car started like a charm. Give this a try before putting out a lot of money on things not needed.
