Next day went to it it started , switched it off it wouldn't start again, it now starts once a day when cold when its started it will drive for ever without stopping its only when switched off it will not start. What has been to do it since is a new camshaft sensor replaced no difference to it.checked for air lock in fuel tank that's ok.tried the gear change lever that's ok. took it to a garage in France they looked at it got it started 15 times by messing around under the dashboard i took it away again the same thing happened started wont start when warm. the garage said bring it back we will have a look at it its been there 3 weeks now they said they need a wiring diagram , it does not have seemed to moved in 3 weeks ,can any one help me source one please , the problem is im English and do not speak French so its a problem as they dont fully know what im saying and vice versa but this would help out a lot , and has any one else had this problem econline powerstroke 7.3 1995 350 its on a camper Fleetwood Tioga Kind regards Dave

By no start do you mean it will crank and not start or ot will not do anything when you turn the key?

I had similar problems this summer with a crank but no start condition after the engine was warm. I finally took it to the diesel shop and it turns out it was the ICPR (ignition control pressure regulator). Hope this helps.

I just bought a beat up 2001 F250 with less miles (103,000) than my 99 but in way worse shape. The previous owner couldn't make it run. I got it started but after I run it a bit it will not restart. It will not crank. If I turn the key on and run a jumper from the battery to the wire going to the starter solenoid it will crank and start. Not wanting to spend alot of time troubleshooting this issue I just ran a wire from the battery to a switch on the dash and then to a relay that i wired to put power directly from the battery to the starter solenoid wire. Now if it doesn't crank when I turn the key I just push this button and I'm off and running,
