What's the reason for Wuling Zhiguang failing to start?

[DiMaggie]

The crankshaft position sensor of the vehicle has malfunctioned, resulting in the failure to start. Below is relevant information about Wuling Zhiguang: 1. Introduction: Liuzhou Wuling independently developed models that comply with international safety and environmental standards. 2. Comfort: The comfort of the control mechanism has been improved. Compared with the 2006 Wuling Zhiguang, the 2007 version has made more optimized adjustments to the driver's seat, control pedal angles, gear lever, and handbrake based on ergonomic principles, and has also adjusted the steering wheel angle. Taking the change in the angle between the leg and the ground level and the foot's control angle over the pedals as examples, by adjusting the throttle pedal angle to a comfortable range, it helps relax foot tension and avoid ankle soreness during long drives.

My friend's Wuling Zhiguang had the same issue last week, the starter makes noise but just won't fire up. It might be a weak battery, especially in winter when battery drains faster. Use a voltmeter to check - if it's below 12V, you'll need to charge or replace it. Fuel system problems are also common - either the fuel pump isn't working properly or the fuel filter is clogged cutting supply. When there's too little gas left in the tank, it can't draw fuel either. Aged ignition coils or severely carbon-fouled spark plugs can prevent ignition - this is the most frequent issue with older cars like this. There are also minor problems like worn starter gears or blown fuses, but it's best not to tinker yourself. The most reliable way is to take it to a repair shop and scan for trouble codes with their diagnostic computer.

My Wuling has been running for six years, and I've encountered two instances where it wouldn't start. The first time was because I forgot to turn off the headlights, which drained the battery, and jump-starting solved the issue. The second time, the starter motor was spinning but the engine didn't respond. After inspection, it turned out to be a fuel system problem—the fuel pump's plug was loose, causing poor contact. Other possible reasons for starting difficulties in this car could be a faulty crankshaft position sensor, the anti-theft system being mistakenly triggered, or wear and tear on the ignition switch. If turning the key yields no response at all, first check if the dashboard indicator lights come on. If they don't, it might be due to a faulty main relay. It's recommended to try turning the car key on and off several times, as sometimes it's just a matter of poor contact.

There are three main systems to check if Wuling fails to start: electrical circuit, fuel system, and ignition. For the electrical circuit, check if the battery terminals are oxidized or loose, and measure whether the voltage reaches 12V. For the fuel system, listen for the fuel pump's working sound—a humming noise at the rear of the car indicates normal operation. For the ignition system, inspect the spark plugs for sparks; pull off the high-voltage wire and bring it close to metal to see if it sparks. Automatic transmission models may lock the start if the gear is not in P, while manual transmission vehicles require the clutch to be depressed when starting. Older cars are prone to short circuits due to aging wiring, especially after rain. If the starter motor spins without engaging, it might be an issue with the starter gear, and a clicking sound usually indicates a dead battery. If the cause remains unclear, avoid forcing it and seek a repair shop for convenience.

Difficulty starting? First check the easiest parts: see if the remote key battery is low, try using the spare key. Open the engine compartment to check if the battery terminals are loose or have green corrosion, rinse with boiling water and tighten them. Then check the start-related fuses in the fuse box, usually labeled ENG or ST. Does the fuel gauge show there's still fuel? Sometimes the fuel float gets stuck and gives inaccurate readings when there's actually no fuel. If you can hear the starter motor turning but the engine won't start, it might be severe carbon buildup requiring throttle body cleaning. Finally, consider faults with the crankshaft sensor or camshaft sensor - if these fail, the ECU won't receive signals and won't inject fuel.

Wuling vehicles are prone to difficulty starting in rainy weather after prolonged use, as is the case with my car. A damp ignition system significantly affects startup; check the high-voltage wires and distributor cap for cracks. Insufficient fuel pump pressure needs testing, with the normal value maintained at 3 kg. Worn starter motor carbon brushes can cause idling noise, which can be alleviated by adding some grease during maintenance. Another often overlooked issue is poor contact due to rusted ground wires—focus on inspecting the black ground wire from the battery to the chassis. If you smell gasoline when attempting to start, it’s likely that the spark plugs are flooded with too much fuel; try pressing the accelerator fully and then starting. It’s best to note the symptoms, such as whether the engine light on the dashboard is on, and communicate them clearly to the mechanic.
