What are the reasons for a Jinbei vehicle having power and fuel but failing to start?
2 Answers
Jinbei has power and fuel but fails to start for the following reasons: 1. Spark plug damage: Check the spark plug to see if it is aged or has heavy carbon deposits, and replace it with a new one if necessary. 2. Poor contact in the high-voltage line: Use a multimeter to test whether the resistance is normal. 3. Ignition circuit failure: Use a multimeter to check for open circuits. 4. The vehicle is too old: The fuel line is severely aged, and the fuel supply cannot keep up when starting the vehicle, often causing failure to start. Therefore, when starting, slightly press the accelerator pedal to speed up the fuel circulation, making it easier to start.
I've driven Jinbei vans for many years and encountered several instances where the vehicle wouldn't start despite having both electricity and fuel. This usually isn't a single issue but rather multiple systems failing to coordinate. Regarding ignition, severely carbon-fouled or aged spark plugs may fail to generate sparks, and a damaged ignition coil won't fire either. Although there's fuel in the system, the fuel pump might not be working, failing to provide pressure; or the injectors could be clogged, preventing fuel from entering the cylinders. Electrical components like faulty relays or blown fuses can shut down the entire circuit; sensors such as a failed crankshaft position sensor will prevent the ECU from knowing when to ignite. If the starter motor turns but the engine doesn't fire, focus on checking ignition and fuel delivery. I recommend a step-by-step approach: first listen for the fuel pump's humming sound during startup, then check if the spark plugs need replacement. Don't rush into major repairs—many issues stem from accumulated minor faults.
