Problem overview

Some Oldsmobile Silhouette owners report experiencing starting issues even after replacing ignition components, which may be attributed to several underlying problems. These issues can include a faulty ignition coil that fails to provide the necessary spark to the spark plugs, as well as malfunctions in the Ignition Control Module (ICM), which controls the coil circuits and can lead to a lack of spark. Additionally, some owners find that damaged or worn-out plug wires disrupt the flow of electricity to the spark plugs, further complicating starting efforts. Problems with crank and cam sensors can also affect spark timing, making it difficult to start the engine. For those encountering these persistent starting issues, it is advisable to check these components and consider testing the ICM and the crank and cam sensors for proper functionality.
