Q: How to check Neutral Safety Switch for Pontiac Fiero?
A: Firmly apply both the parking brake and the regular brakes. If the engine starts, be ready to turn off the ignition promptly. Take these precautions because the vehicle could move without warning and possibly cause personal injury or property damage. On automatic transaxle vehicles, try to start the engine in each gear. The engine should start only in Park or Neutral due to the Neutral Safety Switch. On manual transaxle vehicles, place the shift lever in Neutral, push the clutch halfway and try to start. The engine should start only when the clutch is fully depressed because of the Neutral Safety Switch.
