Daewoo Lanos Won't Start After Timing Belt Change? Troubleshooting

Common Causes

• Incorrect timing belt installation – off by a tooth disrupts engine timing.
• Tensioner malfunction – improper tension causes slip.
• Crankshaft/camshaft sensor damage – ECU loses sync for fuel/spark.
• Electrical connection issues – loose/disconnected wires.
• Piston-valve interference – belt skip causes mechanical damage.

Additional Checks

• Vacuum lines/hoses for leaks.
• Ignition system function.
• Fuel pressure within spec.

If unresolved, consult a professional mechanic.
