Ford V10 - Starting issues when warm

[rdeboer]

I have a 2001 Georgie Boy, Cruise Master that runs great until I shut it off for fuel, etc. When warm/hot, it will not restart until cooled down, typically at least 1/2 hr??

Could be a host of issues... anything from vapor lock (try venting the gas cap before cranking it over) to a cracked distributor cap. (I had this happen on a honda accord... the cap would expand when hot and the crack would get big enough to cause a no start scenario).

Check the basics... you need fuel, oxygen and a source of ignition.

Does it turn over but won't start, or does not turn over at all?

Should not have vapor lock on fuel injected motor and v10 does not have a distributor cap, it has COP coil on plugs.

It is not likely vapor lock because it is a pressurized fuel system. However, if there is some vapor lock (typical in hot weather with winter blend fuel), keep the key on for 10 seconds and restart. This will help with that. The fuel cap release will do nothing for that. This engine does have a solenoid that controls idle. They can stick. When cranking, just slightly apply some gas pedal. This will allow air into the intake and should start. If the gas pedal is sticky, this indicates a build up on the throttle body. This can be easily cleaned out. You can also try to hold the gas pedal wide open throttle. If you do this and then crank the engine, the fuel injectors will remain off. If it starts, suspect a possible issue with flooding. If there are some leaking fuel injectors, this can cause an issue.
