Default Re: 2002 Saturn SC1 coupe has security issue

In theory (without exceptions), once Passlock security is ON, this usually means Passlock disabled itself to prevent interfering with everyday starting. The only time Passlock disables injectors is when security flashes quickly. There are several Passlock modes; a)off, b)using remote to Lock doors with security blinking once every few seconds/Passlock enabled, c) security indicator flashing quickly, indicating a theft attempt was made/ignition lock cylinder destroyed along with the Passlock sensor detecting lock cylinder rotation with Passlock programming in the bcm sending a disable signal to the pcm to actively disable injector operation, and d)Passlock security indicator always on, indicating Passlock self tests failed and disabled security, allowing starting with zero theft protection. According to your descriptions, you're in mode D - security indicator ON, Passlock disabled. To verify Passlock isn't disabling injectors, remove spark plugs and examine them for fuel.

For whatever reason whether you or the thief destroyed the ignition switch mechanics, the Passlock sensors are probably destroyed too. Three wires make up wiring for the Passlock sensor next to the ignition lock cylinder. Once destroyed, Passlock cannot perform its own self tests every time remotes are used before starting. With the sensors broken, the Passlock program residing in the body control module (bcm) determines Passlock failed and disables itself while turning on the security indicator (always on) to alert the owner that Passlock failed and cannot provide theft protection. You should be able to start and drive.

If in mode D, several starting attempts without the engine firing up can be either a fuel or spark issue. Removing plugs should reveal wet soaked plugs, verifying injectors and fuel pressure. You can check for spark too with plugs removed. After noting firing order, remove coil wires from both ignition coils and have someone start the engine while you observe for spark across both coil towers
