For common car owners, in the face of vehicle failure, they will be helpless. First come to understand the engine-related issues. When the engine can not start, how to troubleshoot?
First of all, check the electrical circuit: Check whether electrical circuits including distributors, spark plugs, high-voltage wires are malfunctioning due to rain and dampness. Remove damp parts and dry them with a hairdryer or re-install them after natural drying.
Secondly, check whether the spark plug is damaged. If damaged, just replace a new spark plug. Generally speaking, the spark plug used in cars ranges from 20,000 to 30,000 kilometers.
Then, check whether the battery voltage is adequate. Many batteries have designed observation holes for testing. When they are green, they can be used normally, appear black, need to be supplemented or maintained, appear white, and the batteries should be replaced.
Finally, check whether the lights are turned off at night. If you forget to turn off the lights when parking, you will run out of power. If so, twist the ignition switch in ON position, put the car in second gear, step on the clutch, and drag it with the car. When driving to a certain speed, loosen the clutch, the car will start naturally. This method is applicable only to the failure of insufficient power. If there is a problem with the ignition system, this method not only can not work, but also may have a bad effect on the ternary catalytic converter, and some cars will damage the timing belt, leading to serious mechanical failure. Vehicles with automatic gearboxes can not be started by trolleys, but can start the engine by connecting the batteries of another vehicle with a straddle cable.
