01 GP won't start

I was having some trouble with my key for a while before it finally broke. I wasn't sure what to do so for the time being I installed a switch and push button to run the car which ran the car fr about 3 months. One night I was idleing the car just shut off and would not start anymore. I completely replaced the entire steering column and it still won't start. When I turn the key on i'm not getting any power back to the feul pump and i'm not getting any spark from the coil packs either. I have checked every fuse in the entre car and the are all good. I was wondering maybe if i have to reset the computer or what?

I just had to replace my steering column and I can't get any spark form the coil packs and n power tot he fuel pump. Also when I turn the key on, after a few seconds the OBC starts flashing "0" on all the options. Has the security locked up the system and how do I reset the computer?

First off, year make, engine and trim level of your car would be helpful.

You're going to have to have the security system reprogrammed to learn the new key/ignition switch, which has to be done at a dealer.

I called the dealership and they're going to get t done today..thanks for the info!:)

I noticed your two threads/posts had what appears to be similar issues so I have merged the threads together to cut down on possible confusion and redundant answers.
