What are the reasons for a HOWO truck not starting but having power?

[VonMalia]

There are several reasons why a HOWO truck may not start but still have power: 1. Insufficient fuel: When the fuel gauge is near the warning position, refuel promptly. Do not wait until the tank is empty to add fuel. Otherwise, it can easily shorten the engine's lifespan. 2. Incorrect gear position: Generally, the P or N gear is the correct position for starting an automatic transmission vehicle. Placing the gear in R or another position not only prevents the engine from starting but also poses safety hazards. Carefully check if the gear is in the correct position. If not, adjust it promptly. After correcting the gear position, try starting the vehicle again. 3. Electrical or electronic faults: Electrical faults include blown fuses, open circuits in the high-voltage coil, open circuits in the low-voltage circuit, detached central ignition wires, leaking distributor rotors, or damaged spark plugs. Electronic faults mainly refer to the malfunction of the central computer control board. 4. Fuel system faults: Possible fuel system faults include a malfunctioning fuel pump, blocked fuel lines, clogged fuel filters, carbon buildup on spark plugs, or damaged fuel injectors.
