PASS KEY II (2) IGNITIONS CAN NOT BE SHUT OFF. THEY ARE COMPUTER CONTROLLED. MY EXPERIENCE WITH THIS SYSTEM WAS THE LOCK CYLINDER HAS 2 WHITE WIRES COMING OFF IT RUNNING DOWN TO THE WIRING HARNESS ON THE FIREWALL ON THE LEFT SIDE OF THE STEERING COLUMN. THE WIRES PICK UP A SIGNAL FROM THE CHIP IN THE KEY TO TELL THE COMPUTER THAT IS THE RIGHT KEY AND ALLOWS THE CAR TO START. SOMETIMES ONE OF THOSE 2 WIRES GETS A BREAK IN THEM AND THE PASS KEY II (2) SYSTEM CAN'T RECOGNISE THE KEY AND SHUTS OFF THE FUEL PUMP AND STARTER. USE CAUTION WHEN WORKING WITH THESE WIRES AS THEY ARE VERY SMALL AND CAN BREAK VERY EASILY, BUT I THINK THAT COULD BE YOUR PROBLEM. THE WIRES CAN NOT BE REPLACED BECAUSE THEY ARE HARD WIRED INTO THE IGNITION LOCK CYLINDER. REPLACEMENT OF THE CYLINDER IS MOST LIKELY NEEDED. SOMETIMES YOU MIGHT GET LUCKY AND CAN REPAIR THE WIRE ENDS AT THE FIREWALL AND MAKE IT WORK TEMPORARILY. LOCK CYLINDERS COST ABOUT $120.00. FROM THE DEALER. DON'T TRY THOSE CYLINDERS THAT SAY THEY BYPASS THE PASS KEY II (2) SYSTEM. THEY DON'T WORK ON THESE CARS.
