What are the reasons for the Aoling truck being hard to start?

[DeMalia]

The reason why the Aoling truck is hard to start may be due to fuel quality issues. It is recommended to troubleshoot in the following order: It could be poor fuel quality. New vehicles nowadays generally have few problems, so this possibility is relatively high. It could be an ignition issue—check the spark plugs and ignition coils. If the color and wear are normal, they can be left alone; if not, they should be replaced. At 2,900 kilometers, even if they are wear parts, they should still be under warranty. Additionally, the root cause of insufficient ignition energy should be identified and resolved. It could be poor fuel injector atomization or poor fuel line sealing—check these in order of difficulty. It could also be poor intake or exhaust flow—check for any blockages. There are mainly three reasons why an engine fails to start: Electrical circuit failure; fuel system failure; lubrication system failure. For diesel vehicles, depending on regional temperature conditions, air may be trapped in the low-pressure fuel line. It is recommended to use a hand fuel pump to bleed the air or have it checked at an after-sales service station.
