Question
My pickup starts fine when cold, but when its warm it is very hard to start. I crank the engine, then I stop cranking then crank again before it will start.
Thanks

Answer
It is probably the coolant temperatur sensor causing it to run rich when hot putting too much gas in the engine when it is warm. This will cause it to have the symptoms of "flooding" when you try to start it. It should be located on the intake near the thermostat and have maybe 3 or 4 wires going to it
