5. Bad Air Filters
If the air filters of your car are clogged, broken, or damaged, you will find it hard to start your car smoothly. When the air filter is damaged, the air cannot easily enter the engine. Thus, the lack of air results in making the air filters dirty and clogged.

7. Low Compression
You can find it hard to start your car or any other vehicle if there is low compression in diesel engines. When you operate your car, varnish contamination, sludge, and carbon deposits are formed inside your vehicle’s engine. No doubt, this process is inevitable. After some time, a situation occurs when the carbon deposits do not let the compression rings work properly.
In this situation, the compression falls. You will see that the pressure has become insufficient that it cannot ignite the fuel mixture. You can prevent this issue before letting it get worse. You can use the method of engine flush for cleaning the carbon buildups and maintaining the compression level.
