AFTER READING ALL SEARCHES ON VATS & STILL NO SOLUTION TO 90 ELECTRICAL PROBLEMS (PAST POST) WHEN INSTALLING VATS BYPASS IS IT JUST BYPASSING STARTER RELAY OR DOES IT BYPASS VATS GROUND SWITCHES INSIDE CCM. I JUMP STARTER RELAY WITHOUT BUYING $50.00 KIT.MAYBE THE ANSWER WHY I HAVE NO INJECTOR PULSE BECAUSE CCM HAS A FUEL ENABLE GROUND SWITCH IN IT SOMEWHERE?

The computer gets a signal from the VATS module that the pellet is correct, then the computer closes the start enable relay and allows the injectors to pulse. When you bypass VATS you make the VATS module believe that the correct pellet is in the ignition key. I don't know what year it began, but later C4's have the VATS function inside the computer and you must insert the key before starting the car making it impossible to bypass VATS.
