Hello .. thanks for the donation .. much appreciated

Was the immobolizer the fault before you replaced the ignition switch (ie.) was the vehicle immobolized before you replaced the switch and this is why you replaced the switch ? .. let me know

OPERATION
Anti-theft system is "armed" when all windows are closed, ignition key is removed, and doors are locked. When forced entry is attempted, alarm warning system will trip, causing horn to sound intermittently and exterior lights to flash for 3 to 7 minutes. On models with a starter interrupt relay, starter will cease to function. System is "disarmed" by unlocking either front door with key or by turning ignition on.
TROUBLE SHOOTING
SYSTEM WILL NOT DISARM
Check lock cylinder switches for looseness. Try to disarm system using key in passenger door lock cylinder. If system disarms, check for open circuit in wire leading to lock cylinder in driver's door.
SYSTEM WILL NOT DISARM FROM EITHER DOOR
Hold lock cylinder in unlock position with door key. Check for open circuit in wire coming from controller.
SYSTEM GOES OFF BY ITSELF
Check for too close adjustment of door jamb switches. Check jamb switches and ground wires for corrosion. Check lock cylinders, tamper switches and door jamb wires for looseness. Check diodes.
SECURITY LIGHT INOPERATIVE
Check fuses or bulb. Check wiring to bulb for shorts or open circuit.
SECURITY LIGHT GLOWS BUT SYSTEM WILL NOT DISARM
Check lock cylinder switches for signs of tampering. Check switches for looseness. Check for frayed or pinched wires to cylinder or jamb switches. Check jamb switches for proper adjustment. Check circuits external to controller. If all circuits are okay, repair or replace controller and relay.

Check switches for looseness. Check wire between door jamb switch and security switch for pinch or fray. Check wire leading to tamper switch. Check door lock switches and wiring.
