Hi I have a 2002 alero the car started great when I got it. Now the security comes on at times and won't start but will turn over and starts when the batt is almost out of power and fires right up or I got to turn it over till it dies and get a boost. I have cleaned the tumbler oiled it and now got the tumbler kit with the magnet and wires. Put it in and it stared all day yeasterday till today. The thing to replace from what I know it the black box in the dash witch is $80 used. So far I have put out almost 400 in 3 months. Will this be my last thing to fix or could it be more things cause it never seams to end.

I would recommend the resistor, because the toggle switch will only work until you disconnect the battery or your codes get cleared by someone. Then you will have to hope the key will work one more time.

GM bulletin
 

As I read the GM bulletin, 'turn the key off, and then cut the yellow wire'. My '01 Alero won't start at all, just cranks. This procedure did not work for me. I have read many other comments saying that the yellow wire needs to be cut w/engine running. Since mine won't start, I am unable to do this and this bulletin did not work for me. My ignition key does not have an exposed 'chip'. I will try to read the resistance from the yellow wire, then do the resistor procedure. Trying to avoid the $300.00 newrockies module, but if I can be fairly certain that will work, then I can salvage this $2,000.00 car?!

I also have the same problem.
 

No crank no start. Tried resistor bypass doesnt work. Ajy advice?
