Fouled Plugs: Spark plugs create the spark which allows the vehicle to burn fuel. Fouled plugs are one of the most common reasons for a hard starting engine.

What causes long cranking?
A bad coolant sensor, a bad throttle position sensor (TPS), a bad fuel pump or a plugged fuel filter can all cause a lean condition causing long cranking times.
What causes hard cold starts?
Causes of Hard Starting When Engine Is Cold Weak ignition spark. Faulty sensors. Poor fuel delivery. Bad electric current flow.
What are the most common engine starting problem?

Why is my car battery not charging?
A: Battery not charging because of age 60 months / 5 years they tend to fail, have it tested 12.6 volts and a load test based on cranking amp hours. It can also be loose or corroded terminals connections on the battery preventing it from charging or cranking, next the alternator may have stopped functioning, (100,000 miles there tired) letting the battery discharge and stalling the car out then only a click when you try and restart.

What happens when you start a car in winter?
Cold start car problems are the most common when starting automotive in winter. Extreme cold can affect the battery performance too. It produces electrons through chemical reactions, but the process slows down in low temperature. As a result, it generates fewer electrons and supplies less than sufficient energy to the starter.
How to start a hot start?
A: For the hot start, hold the gas pedal to the floor while you turn the key to see if that does anything. If it helps then you may have a leaking fuel pressure regulator or fuel injector sending fuel into the intake on hot shut down. The other possibility is heat soaked ignition components.

The fuel can get thicker for two reasons – low temperature and not doing an oil change at the recommended time. As you know, a liquid cannot flow quickly if it is condensed. In that case, the engine has to push around a lot to spin and start because not much oil can get into the fuel line and the engine.
