Description

How the starting system works:

Neutral safety switch

Automatic transmission range switch Automatic transmission range switch.For safety reasons, the starter motor can only be operated when the automatic transmission is in Park or Neutral position. In a car with a manual transmission, the engine can only be started when the clutch pedal is depressed. In vehicles with a manual transmission, the clutch pedal switch completes the starter motor circuit when pressed. In cars with an automatic transmission, the transmission range switch allows the starter to operate only when a transmission is in Park or Neutral.

Starting system problems

Starting system problems are common and not all of them are caused by a faulty starter motor. To find the cause of the problem, the starting system must be properly tested. If when you are trying to start the car, you hear that the starter cranks as usual, but the car doesn't start, then the problem is most likely not with the starting system. Read more The engine cranks but won't start. Here are a few common starting system problems: Battery terminals Corroded batter terminal Good connection. The battery is very common to fail. Sometimes one of the electrical components that was left on or has a defect causing parasitic current draw drains the battery. Sometimes, an old battery can just die one day, with no warning. In either case, if the battery is low on charge, it won't have enough power for the starter motor to turn over the engine.

If the battery is low on charge, when attempting to start the engine you might hear a single click or repeated clicking, or the starter may turn over slowly and stop.

Poor connection at the cable terminals can cause the starter not to work or run very slow too. Often the battery terminals or the ground cable connection get corroded causing starter problems (see the photo above).

Corroded starter terminal Corroded starter solenoid control terminal Sometimes the starter control terminal gets corroded (in the photo) or a starter control wire gets loose or disconnected from the terminal causing the starter not to work. For example, this corroded starter control terminal was the cause of a no-start, no-crank condition in the Mazda 3. We only noticed this after disconnecting the control wire connector. Cleaning the terminal and replacing the connector solved the problem.
