A bad spark plug often causes an engine cylinder to misfire or sound like its struggling. The sensors are a fairly basic on/off switch type, and they seldom cause problems. Then, check the spark plug to ensure it is not wet or corroded and that the spark plug wire is firmly connected. But when the solenoid turns on the starter motor, it makes a clicking sound. To access the brake switch, remove the air duct mounting screws and pull off the air duct. If you hear a clicking sound but the starter motor isnt moving, the solenoid could be engaging but not receiving enough battery power.
