Why the engine can't catch fire

There are several reasons why the engine doesn't catch fire:

1. The battery is low or dead. If the engine can't start, test the battery first. It is necessary to find out whether the engine cannot be started because the battery is low and needs to be recharged.

2. Engine starting system failure. For the fault that the engine can't start, the first thing to do is to detect the circuit in the engine starting system. From the most basic form of composition, the circuit of starting system generally includes the following basic parts, namely, battery, starting motor and cables connecting these parts. Of course, in addition, the ignition switch, starter relay or electromagnetic coil, and vehicle-mounted anti-theft system are also important components of the starting system. The startup system is damaged and needs to be repaired in 4s shop.

3. Engine ignition system failure. In the early ignition system, it was convenient to remove the ignition coil and then use the electric spark detector to detect whether the electric spark was normal. If the ignition system fails, you can clean up the carbon deposit or replace the spark plug.

These are the reasons why the engine won't catch fire. We can check them one by one.
