I have a 1993 Pontiac Bonneville SSE 3.8, I tried to start car by using a screwdriver in the ignition and now my car wont start it started by jumping the starter but wont stay running. Now I have a set of...

What you need to do there is to turn the ignition switch on and off three times, leaving it on the third time. Leave it on for about fifteen or twenty minutes and the light should become steady. then you can start the engine. (I usually put a jumper battery on it to make sure it does not knock down the battery too far) If that fails to work, then the problem likely is in the switch or the security module.

Left the key in ignition went in the the house for about 15 min left rear passenger side door open came back out car would not start... tested batery,sarter,fuses relays everything we can think dash lights...

Could be a few things. Does the key have a raised black dot on both sides? My 93 Bonneville did but not sure if they started using the PASS system on 92. It is actaull an internal resistor that has to be correct resistance when you try and start the car. Sometimes that gets dirt on it and if you try and start the car it will go into a mode where ever with the correct key it won;t start for 30 minutes or so. Other thing I would check is the neutral safety switch. Try to start in neutral (or even other gears with the brake on).

93 pontiac bonneville security light stays on and car won't start.

You can easily bypass the entire VATS system. There is a clear write-up here on this website: This was the only thing that saved my 94 Park Avenue with the same security system.

93 bonneville wont start

Wow...this could be a BIG problem...unless you have pretty good mechanical abilities. Your BCM (body control module) is faulty. If it's any consolation, you're not alone. There are two schools of thought as a repair and often ends up being a "trial n error" type of repair. One is to match the rating of the small metal chip in your ignition key with a resistor (RadioShack) and splicing the resistor into the ORANGE wires leading from the ignition to the BCM. The other is to replace the BCM with a junkyard piece and IMPORTANTLY make sure you get the ignition key that goes with it.
Good Luck

Security light flashing, does not turn over, do i replace ignition or ecm or both? Do i need new key if i replace ignition?

Chances are the wire going to ignition broke allowing the security to start flashing.this will keep the
car from cranking.On my 93 bonneville I went to Radioshack and got a 680 ohm resister,cut the 2 small
yellow wires on lower steering column under dash,soldered resister to the 2 yellow wires coming from harness.Cost of repair..$1. you can read the resistance on the key by using ohm meter on each
side of chip in key
