Buick LeSabre Problems

Car Won't Start Because of Anti-Theft System That Uses Raised-Chip Key

Problems with the anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The the key and ignition lock cylinder must be replaced to correct this condition.

Hydro-Lock Due to Internal Coolant Leak From Intake Manifold

The upper intake manifold may develop an internal coolant leak causing one or more cylinders to fill with coolant. This can cause the engine to "hydro-lock" and not turn over. Removing the spark plugs will allow the engine to turn over pushing the coolant out of the spark plug holes. Replacing the upper intake plenum and gasket is commonly required to correct this condition.

The engine can be very difficult to start after this problem has been repaired, it can be helpful to clear as much of the coolant from the intake manifold and cylinders as possible before reassembling the intake manifold.

Engine Control Module (ECM) can fail

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.
