I have a 95 Ford Explorer and it runs just fine except when the weather gets hot, sometimes it has trouble starting. It starts and immediately dies. Sometimes it'll start if you put it in nuetral and rev up the engine for a minute or two. It only does this when the weather gets hot outside. Any other time (Fall, Winter, at night, etc.) it starts just fine with no problems. Any ideas on what could be the reason?

Possibly a weak fuel pump.

I'll go along with Bird's answer about the leaking fuel injector possibility. To help prove it, the next time it happens, push the accelerator all the way to the floor and see if it starts better. That opens your throttle plate wide open to let as much air as possible into the engine and puts your computer into the "clear flood" mode where it stops injecting any more fuel into your engine. When the engine's flooded, you don't need any more fuel! You also have a coolant temperature sensor that tells your computer how hot the engine is. Maybe you have an error code in your computer to help diagnose the problem.

Vapor lock in the fuel system. Look for fuel lines (esp steel ones) running close to exhaust or uninsulated by the engine block. Fuel line gets hot and a bubble of vaporized gasoline forms in it, blocking the fuel flow.

Could be from a leaky fuel injector causeing a over rich condition in one or more cylinders,if it smokes a little black out the exaust when it cranks I would look into that,or possiable vapour lock in the fuel system from heat soak.

The reason is that the motor gets hot and causes the motor not to start. if you could get the motor to start and let the radiator cool down the motor if not and dont know if it will work but put some water on the motor well dont try that unless u want to.

it might be the viscosity (thickness) of the oil you have in your car. different kinds of oil have a variartion of thicknesses at different temperatures, so you may want to change your oil depending on the maintenance guide
