Suddenly when I start my 2000 Grand Am with either the key or the remote starter, it shuts off immediately. The security light stays on with the key in the on position but does not flash. I have disconnected the remote starter and battery to try to reset the computer. The "check engine" light is not flashing with a code. I have been told that the ignition switch may have gone bad and the computer thinks there is a problem, I'm not sure about this. Any help is greatly appreciated.

Could be an ignition switch, fuel or spark problem

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, cap and rotor /distributor pick-up coil, ignition control module, ECM, Ignitor cam and crank sensors- Note: If it doesn't apply disregard it
