it now appears that i probally have an ignition switch problem or key tumbler problem on my grand prix(counsel shifter-automatic),i can't believe the price of an ignition switch,just how hard is it to change one out, and also the key tumbler??i thought it was the security system,but a mechanic by passed it and the car was still doing the same thing,key would stick in cylinder a few times,then if you went to acc. then to start it would work but a few times it was dead then on the third or forth try it would start. thanks
