What Causes Difficulty in Starting a Car?

[DeJaxson]

Here are the specific reasons for difficulty in starting a car engine: 1. Carbon deposits in the car cause ignition difficulties. At idle, it may also be accompanied by slight shaking, which can be resolved by cleaning the throttle and fuel injectors. 2. Weak ignition energy from the spark plugs. If spark plugs are not replaced after the maintenance cycle, their ignition energy decreases severely, leading to misfires. 3. Insufficient low-pressure fuel supply. Low fuel pressure in the low-pressure fuel line directly causes the engine to require a second ignition. Specific checks should include the fuel pressure regulator, fuel pump, fuel filter, and internal lines. 4. Battery depletion. This requires jump-starting the car with another vehicle or battery. 5. Incorrect engine timing. Mismatched engine timing or skipped teeth when replacing the generator belt in certain engine models can cause difficulty in starting.
