i took a look at that link but so far have not been able to fix this. i went back to auto zone earlier today and had them hook the scanner back up to the car. before i did though i turned the key and nothing, no cranking or attempt at all, but when we plugged the scanner in the car started right up and ran normally. i left it on for a minute, and as soon as i pulled the scanner out of the obd II port under the dash, the car immediately dies. so, from this little experiment i now know that my engine isn't seized, the computer is goo, the starter is good, the battery is good, the fuses are good, the ignition switch is good. i'm not sure where this leaves me? i want to lean towards something along the lines of theft deterent, but don't really think so. what i'm thinking is that when the scanner is plugged in the computer is 'jumping' terminals and by-passing whatever is causing my problem, therefore.... a bad sensor? what the heck could be causing this? i know on my firebird people will sometimes use a paper clip to 'jump terminals' on the plug under the dash and it bypasses the computer signal to the fuel pump and will automatically power the fuel pump from 12v battery power. it seems like that is more or less happening in this case. if thats the case, is there a way i can actually bypass this with a paper clip in order to drive the car home? does this clue help narrow down my faulty sensor/circuit? another thing i thought i would mention is that the scanner is pulling NO codes and when they had earlier hooked up the scanner, and also when i went back and verified the car would start with the scanner on, the a/c kicked on like it does when the computer is re-set. problem is i hadn't disconnected the battery since it had initally stalled and i wanted to try and re-set the computer to hopefully start it. obviously i have some sort of electrical gremlin, but any help i can get would be appreciated because i don't know where to start. anyone have a diagram of the obd II 'pigtail' connector under the dash?
