Car Turns Over but Wont Start

Car Turns Over but Wont Start

The car turns over but won't start. The car is cranking slowly however, it will not start. If the car is turning over slowly and will not start the possible reason is the battery.

The possible reason why the car turns over but won't start
1) The battery terminal is corroded
2) The battery is weak

To determine the reason why car turning over slowly, do the following:
1) Turn on the car headlights then start the car engine while the headlights were on. Observed the brightness of the headlights if there are changes during starting. If there is any change in the brightness of the headlights then the problem is battery related. But if not then it is not battery related.

2) Open the hood of the car locate the battery and check the battery terminal, inspect if there is corrosion on the terminals. This look like a white cruddy substance that is a presence on the cable end and on the top of the terminals. If there is a presence of this substance then this restricts the flow of the current into the starter that is why the car won't start. But if the substance is not present on the terminal then this means that the battery is weak.

What to do if car turns over but wont start?

(1) Corroded battery terminal
Using a wire brush clean the battery terminal, apply baking soda and water on the terminals while cleaning with a brush to help dissolve the corrosion.

After the terminal is cleaned, apply petroleum jelly on the terminals to help prevents future formation of corrosion on the terminals. Make sure that both battery terminals are coated with petroleum jelly.

(2) Check if the battery is weak
Open the battery fluid filler cap and check the fluid level. The fluid level should cover the top of the plates, if not then add distilled water just enough to cover the plates, then jump start the car with a good battery. After the car starts, just keep the engine running to charge the battery, let the engine runs for a couple of hours to give time on the battery to have enough charge to run the vehicle going to the battery shop.


Some batteries have an indicator sight glass on top of the battery that indicates your car battery estate of charge. If the color inside the monitoring indicator window is green, it indicates that the battery power is excellent. If the color inside the monitoring indicator sight glass is black, it indicates that the battery liquid volume is insufficient. If the monitoring indicator sight glass is colorless, this indicates that the battery needs to be replaced. If the monitoring indicator sight glass is colorless, use a screwdriver to lightly tap the monitoring indicator sight glass to drain air bubbles. If the color inside the monitoring indicator sight glass does not change, the battery must be replaced.

Bring the battery to any battery shop and have the battery check to make sure if it needs to be recharged or replaced. Now If the car won’t start on a very cold temperature the problem is because the battery electrolytes freeze up and cannot run the engine. If your car needs to be driven over a long distance or in a hot region or the battery is used for too long, be sure to regularly check the battery power.

Also,  if the car is frequently driven over short distances or is parked and not used for a long time, be increase the frequency of checking your car battery. If for instance the battery is damaged, the battery power will be insufficient, making it difficult for your car to start.

 If the battery has been used for a rather long time, it may not maintain charging efficiency the same as when it is completely new. Likewise, if the car is not used frequently, or the car makes too many short starts or runs in a cold environment, then its battery needs to be charged regularly.

Battery Replacement
If you are to replace your battery,   use a battery of the same model and the same specification as that of the battery your car used. Otherwise, there may be situations of inconsistent dimensions or different terminal positions, thus it is likely to cause battery damage, leakage or fire.
