05 powerstroke wont start hot , If i drive it 5 minutes and turn it off it will crank, hard and fast but wont fire.... wait 2 hrs and no problem... wait an hour and put the pedal to the floor it sputters and will start, fuel pump ??? It runs normal and great when it is running... just if i stop and turn it off.
>>> empty the fuel water seperater.
>>> lucas injector cleaner thru it twice
>>> added more fuel 7/8 full ????

not sure where to start with this one ... thinking electric fuel pump.

Bad egr valve. Clogged with carbon. Cold a egr valve partially clogged will allow cold eg's pass(because there are not as many hot gases), but once it's hot it will stick open and you will get a lean fuel mixture and no start issues, along with poor performance. F250's with power stroke engine from 1999-2005 had all kinds of egr valve issues. Clean your egr valve and you should notice a difference.

That is completly wrong, EGR wont cause a no start when hot, it needs the STC bracket on the back of the high pressure oil pump, the quick connect is leaking. promise.

PS franco, 99-03.5 had no egr valve, 6.0 only, witch is 03.5-07. Good day sir.
