Bypassing Security system
I have a 1995 pontiac Trans Am with a 5.7 . It will crank and run good until you park it. When you park it for a couple hours it will spin over it will not fire up. I have replaced the fuel pump twice , fuel filiter several times, had the computer checked, all sensor replaced including the whole disturber ( which lays under the water pump). When I bought the car the security system was bypassed. I had some trouble in Tenn. and had some KNOT HEAD work on it. They replaced the computer the switch and fixed the wiring problem. That happen before I done all that I did. I feel its the security system that is causing the problem. I need to know how to bypass the factory securtiy systems.?

Re: Bypassing Security system
You should double check to see if this is a vats issue bye using a noid light. You can have the ecm re flashed or install a 50hz modulator. This is put in the wrong section more of a electrical question.
