Can hot weather affect your car starting? In extreme heat, your car may not start because of issues with your fuel. When your engine is too hot, fuel cannot circulate well, making it difficult for your engine to start. To keep your engine running at the correct temperature, make sure to maintain your coolants.
The cold starting issue could possibly be caused by a failing fuel pump or even a temperature sensor. Heat increases resistance in electrical circuits, and it is possible that once the fuel pump has been running for a while, high resistance causes it to slow or stop.
A bad coolant sensor, a bad throttle position sensor (TPS), a bad fuel pump or a plugged fuel filter can all cause a lean condition causing long cranking times.
