its a factory system. my new ignition coil was bad so i didnt get a spark. got a new one and now it tried to turn over like three times but my fuel pump is not working right. some wight two prong silinod thing has a wire short in it. im going to run a wire from my fuse box to the silinod to see if i can get it to fire because now im not getting fuel.

well now we are getting spark and it tries to fire but just wont start up. we think maybe the injectors are clogged or maybe stuck open or that there is water in the fuel because it tries to fire up every now and then after a few minutes.

Well everything works fine. The cps is working all the plugs are firing and I'm getting fuel. I checkeed all fuses and made sure everything was hooked back up. It will crank and fire up but will cut off as soon as I stop turning key. So now I think its the computer

Have narrowed it down to it being an electrical problem with my security system that factory. My friend hocked up a battery charger and smoke started comming out from behind the radio. When I turn the key security doesn't light up anymore so I don't know if its the computer on the driver side firewall or if there's another computer module. I don't know where it looks like or can be located anyone have any ideas?
