Car starting problems

If the car won't start but the battery is good, check the timing belt. The car won't start but the battery works well while starting it just turn over and will not start but the car turns over a lot faster than normal. If the battery works fine the possible reason why the car won't start is the timing belt.

The reason, why the car won't start but the battery, is good

(1) Problem with the timing belt.

Car Troubleshooting

The first thing to check is the battery, open the hood and locate the battery. Using a multi-tester check the battery voltage, the battery voltage should be at least 12.4 V, if the battery voltage is good next to check is the battery condition. Check the battery terminal if there is a presence of a cruddy-like substance on the battery terminals, if there is a presence of this substance, then that is the reason why the car won't start, it is because that substance prevents the flow of current from the battery to the starter. Now if the terminal is in good condition and the battery is good and works fine then the battery is not the problem.

Now start the car, if the car turns over faster than normal then this is an indication of a problem that has something to do with the timing belt. The function of the timing belt is to make sure the valves in each cylinder are closed during the combustion inside the engine cylinder, it is necessary to provide compression. If the timing belt is not functioning properly and has a problem like if the belt is broken, there will be no compression inside the engine during the compression stroke and will cause the car not to start.

The car that is not starting with a good battery usually a broken timing belt or lack of compression is the main reason.

  1. The phrase "turning over" refers to the car transitioning from the starter motor crank phase to the engine running. The quick, repetitive noise that comes from a car when you turn the key when in the on position is called the "crank", referring to the electric starter motor "cranking" the motor to initiate ignition.

    The phrase "turning over" does not refer to the crank, and is a typical misuse, leading to confusion.

    Another cause of a car not starting with a good battery and a noise that could be considered a "fast crank" is a failing starter motor. The "fast crank" will sometimes never turn over no matter how many times it cranks, and continuous cranking in this state will lead to further starter motor damage. An easy way to get a car running with a bad starter requires a medium straight pry bar or "crowbar", a small hammer and a second person. Find the starter motor in the engine bay. Place the pry end of the pry bar or crowbar on the starter motor and LIGHTLY tap the other end with the hammer. Simultaneously, have a second person crank the engine. Nine times out of ten, a bad starter motor will be failing due to small pieces which look like teeth falling off, and tapping the starter motor while cranking allows the motor to find a good "tooth" and produce proper charge to initiate a good electric cycle, and will start the car. This condition will only worsen with time so timely repair is essential.
