Wont start

(1999 Ford F-250 Super Duty)
in Stuart, OK on December 27, 2009
truck was running fine, havnt got it to start since, except on ether. Lift pump good, seems like oil pressure slow coming up, but should stay running once started on ether,but wont. Have a feeling its a sensor, maybe oil temperature switch?

Will start on rther but will not run by itself

How is your glow plug relay behaving? Does it come on for awhile and then go out after a certain amount of seconds if the engine is really cold. And, how are your glow plugs, when was the last time you checked them and replaced them. I used to be a Ford Tech and when a 7.3 would not start when it was cold but would on ether, it was glow plug time, in most cases.
