2004 Impala LS

Engine occasionally fails to turn over. Battery is OK. Unpredictable. After waiting 15-30 minutes, car starts normally. Appears to be linked to relays or other components necessary for engine to start over

  1. My first thought would be the starter or poor connection at the battery. If thee is corrosion present at the battery terminals, clean them first.

    When you hit the key you hear nothing or one hard click?
    One hard click? replace the starter.
    bunch of clicks? replace the battery(doesn’t matter if it tests good)
    hear nothing? check your connections… test for battery positive at the “S” terminal on the starter when someone holds the key in the start position…voltage present, replace the starter.
