    Q:
    How to chek the Neutral Safety Switch on Pontiac Grand Prix? Posted by Petr F.
    A:
    For automatic transaxle vehicles, try to start the engine in each gear. The engine should crank only in Park or Neutral. For those fitted with a manual transaxle, move the shift lever to neutral and push down the clutch pedal about halfway. The engine should crank only with the clutch pedal fully depressed. Make sure that the key can enter into lock position only when the shift lever is in Park (automatic transaxle) or Reverse (manual transaxle). The ignition key should come out only in the Lock position.
