Therefore, many people ask the question, Why is my summer car engine not turning over ? The answer often lies in irregular maintenance of the ignition coil? choosing a good ignition coil is essential for the car to run smoothly without interruptions.
Failure of the electric fuel pump cycle occurs
when the fuel pump fails to pump fuel during car operation. When the fuel cycle is complete, the engine operates normally, and fuel is then pumped automatically based on the pump's movement. If fuel pumping stops consecutively, the car stops working.
Battery discharge
The battery loses its electrical power when it is discharged, causing the car to stop. The battery must be recharged to resume functioning.
Starter motor failure (the starter)
The starter motor is responsible for starting the car's engine and pistons. It is essential to ensure that the starter motor is working properly to prevent the car from malfunctioning.
Tests to determine the cause of car engine not turning over?
The necessary tests to identify the reasons for the car engine not turning over can be summarized as follows:
Regular Engine Oil Check
This involves knowing the suitable types of oil for the car and the recommended intervals for oil changes.
Checking the coolant and brake fluid
Ensure there is an adequate amount of coolant to prevent engine overheating, which can lead to car breakdowns, especially during trips. Also, regularly inspect the brake fluid.
Car Battery Test
Due to various devices in the car that consume battery power rapidly, such as the air conditioner, window motors, and lighting? additionally, battery depletion is considered the primary culprit behind some car engine not turning over issues. For instance, if the car engine not turning over but lights come on, this indicates a battery problem.
Air Filter Inspection
Checking both engine air filters and cabin air quality control filters.
Tire Inspection
Checking the condition of the car's tires.
Transmission Fluid Check
Engine Belt or Drive Belt Inspection
Spark Plug Examination.
Cleaning these plugs from accumulated dirt and debris
