Chery TIGGO 8 PRO: Normal cranking speed but no start; check the wet spark plug scenario

Symptoms

• The engine crankshaft turns at normal speed, but the engine still does not start after repeated attempts. ^[1]

Possible causes

• The manual explicitly states that spark plugs may become soaked with petrol after multiple starting attempts; this is distinct from the battery branch involving no cranking or slow cranking, and does not directly establish that the spark plugs have reached the end of their service life. ^[1]

Checks

• Check for normal cranking, the starting procedure and fuel level; follow the source's instruction to stop repeated attempts, wait and try again. If the engine still does not start, have a qualified technician check the spark plugs and the cause of the fault. ^[1]

What to do

• Avoid continuous starting attempts that could damage the starter motor; if the engine still does not start after waiting, have it inspected. Wetness does not mean new spark plugs are required. ^[1]
