1997 Chevrolet Monte Carlo ProblemsEngine Starts and Stalls Due to Secutiry System Fault
The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
