General Motors has determined that an intermittent no-start condition may occur on certain 1988 Chevrolet Corvette model vehicles. An inadequate wire connection in the lock cylinder can cause the Vehicle Anti-Theft System (VATS) module to sense an incorrect resistance. This causes the VATS to start a four minute lock-out timer during which any further attempt to start the vehicle resets the timer. Most vehicles will start on the next attempt, provided the four minute lock-out timer has completed its cycle.

To correct this condition, dealers are to inspect the lock cylinder connector for the presence of soldered terminals. If the terminals are not soldered (crimped only) the lock cylinder is to be replaced.
