I have a 2001 Gmc Sierra 4.3 Truck
When It is very cold out, It starts right up.
But when it is warmer out It takes a bit more cranking over to start.
Is there a tempature sensor that could be going bad?
Thanks Kelly

No no temp sensor like ambient air from outside except the intake air temp sensor but if it malfunctioned you would see a check engine light coming on, if you have no light it might be time for simple maintenance, plugs cap rotor wires, fuel filter air filter and induction cleaning, if these items havent been done for 30k or so its time, let us know
thanks
