When troubleshooting an Oldsmobile, be aware of common problems associated with various models, such as abnormal clicking noises and no-start conditions on the Oldsmobile Alero and air compressor failure on the Oldsmobile Bravada. As a further example, the Oldsmobile 88 is known to develop engine problems leading to stalling or failure to start.
The Oldsmobile Alero suffers from numerous reported problems, including failure to start as a result of a failed passlock sensor, faulty turn signal flasher causing a clicking noise, and loss of air conditioning functionality. In some vehicles, the intake manifold gasket may start leaking coolant or engine oil, causing coolant to mix with engine oil resulting in damage to the internal components of the vehicle's engine. The passlock sensor failure activates the vehicle's anti-theft system, making it impossible to start. To fix this, replace the ignition lock cylinder.
If troubleshooting an Oldsmobile 88, be aware that vehicles manufactured between the years 1990 and 1999 are prone to an anti-theft problem that keeps the car from starting. This problem occurs as a result of broken wires in the steering column, and requires the replacement of the key and ignition lock to repair. Also, the Oldsmobile 88 is known to have a crankshaft position sensor that is prone to failure.
