Several Reasons for Difficulty in Ignition of the National VI X-Trail
2 Answers
Out of fuel or battery power. Reasons for ignition difficulty include: Fuel system issues; Starter motor malfunction - requires workshop inspection to determine if the starter has insufficient output; Fuel pump problems - leading to inadequate fuel pressure and consequent starting difficulties; Ignition coil or spark plug failure - check for abnormal cylinder compression; Poor contact in crankshaft/camshaft position sensors or engine wiring may also cause starting issues; Battery problems - aftermarket electrical installations may increase risk of power leakage. Causes of prolonged clicking sound during X-Trail ignition: Extended clicking noise during ignition may result from severe throttle carbon buildup - consider cleaning the throttle body and inspecting spark plug ignition performance.
My China VI X-Trail used to struggle with starting in the morning, and I found fuel quality is crucial. The high-pressure fuel pump in this generation is quite delicate; using gas from small gas stations often leads to poor fuel supply. Later, diagnostics revealed the carbon canister purge valve was stuck, causing pressure buildup in the fuel tank. The mechanic said a dirty crankshaft position sensor could also misjudge RPM, and clogged fuel injectors result in poor atomization. A weak battery is another common issue, especially in winter when low voltage makes starting even harder. Now, I only use fuel from reputable stations, and after replacing the battery, it starts right up. It’s essential to check these points promptly.
