1991 Pontiac Sunbird Problems

The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

The ignition module or crankshaft position sensor may fail causing the engine to die and not restart. Diagnoses will be necessary to determine if the module or crank sensor is causing the no start condition.
