Why does my Wagon R’s engine take too long to start in the morning?

Every morning, my 2019 Wagon R takes multiple tries to start. It cranks but doesn’t fire up easily. Once it starts, it runs normally. Could this be due to a malfunctioning crankshaft position sensor o r coolant temperature sensor?

Hard starting in cold conditions is a sign of a sensor misreporting engine temperature o r timing. Likely causes include:

Coolant Temperature Sensor: If it incorrectly tells the ECU that the engine is already warm, it wont enrich the fuel mixture properly for cold starts.

Crankshaft Position Sensor: A weak o r failing sensor may not provide accurate timing signals, especially when the engine is cold.

Battery voltage issue: Although not a sensor, low voltage can affect sensor readings and fuel delivery at startup.
