350 7.3 won't start

went to start this morning like useal ,Stated just fine 3 minutes into warm up
it just stopped will not restart cranks but no go .... replace mech fuel pump
thinking that would solve but no go ... tried to purge lines no good either

Check for spark. What year ?

Sorry I was not paying attention. Try fuel filter. I have seen water block them.

You handle is "Chevytruckin365", is this a Chevy truck or Ford?

350, which 350?

What year?

Diesel or Gasoline (from your description it could be either one)?

Has it acted oddly in the last month or two before this happened?

The Handle is what it is Man ,,, Got two c-10's 87 short Tbi 305 ,one 82 long carb 305 ,, !!!!!!!!!!!!!!!!Back to the FORD!!!!!!!!!!!!!!! F-350 7.3 DIESEL 1997 .....Replaced the fuel filter had a sludge black (oil ?????) on it also replaced the fuel pump on top by the turbo But is there two on this model and if so where?????

This is going to make a mess but crack open all your lines and make sure you are getting good pressure at the injectors.

Pull the valve covers and make sure your valves are opening and closing like they should be.

Check all your glow plugs.

Are you getting any boost pressure at all from the turbo when the engine is trying to start?

Check your exhaust pipe for something someone may have shoved up inside it.

get the computer scaned may be high presser oil senser

Tried tonight to get fuel pressure to lines before they go into injectors (succeded)
Also tried gasing the intake (holding gas soaked rag it air intake fired up several times but would diesel and die -have scanner but nothing shows up everything passes found injector silinoid bolt that held inplace had fallen off and scavanged from my other 96 7.3lit but still no GO HOUSTON!!!!!!!!!!!

Only thing left I can think of is that black goop that was in your filter made its way into the injectors and clogged them, try pulling them out and soaking them in injector cleaner for a while.

The Diesel Mech- I talked to today said that the black sludge on filter is from O Rings on injectors gone bad and is regurgeatating oil through lines into filter
Through back pressure . So am going to replace O Rings tommorrow kit for all 8 injectors bout 135.00$ Will keep posting findings

Still can not get going Replaced gaskets on injectors went with out a hitch ,
next is either oil pressure regulator or (big daddy) Oil pump .....
Does anyone know how to bench test a oil pressure regulator Or on vehicle
it is right side down past the fuel filter kinda hard to get to !!!!!!!!!!!
looks like a magnet switched silinoid but will not energize also chacked on another truck a 96 but still no energize No magnetic pull
