- Engine temperature sensor: A faulty engine temperature sensor can provide incorrect information to the engine control unit (ECU), which can cause the engine to cut out when it is cold.
- Battery: A weak or faulty battery can cause the engine to cut out, especially when the engine is cold and requires more power to start.
- Fuel filter: A clogged or dirty fuel filter can restrict the flow of fuel to the engine, causing it to cut out.
- Spark plugs or ignition coils: Worn-out or faulty spark plugs or ignition coils can cause the engine to misfire and cut out, especially when the engine is cold.
- Coolant leaks: A leak in the cooling system can cause the engine to overheat, which can cause the engine to cut out to protect itself.
- Air leaks: A leak in the air intake system can cause the engine to run lean and cut out when it is cold.
