I changed both fuel filter but now it will not start?

We have a f450 that will not crank no matter what. Ive tried hitting it on starting fluid but no luck. Its getting fuel to the fuel filter and if you turn on the key on the bowl fills up but it is not hitting at all. I am thinking it is a high pressure oil pump but I am looking for a second opinion and hoping it might b something else but I dont have much hope. Any help is greatly appreciated

It will turn over, if it was low fuel pressure injector clogged fuel filter and so it would still hit on ether

It ran fine then he turned it off and when he went back to start it, it tryed to start sputtered then died when tried to start again it just turns over but won't start, we contact a local ford dealer mechanic and he thought maybe it was the cam sensor so we replaced that and it still does the same, also checked to make sure it was getting enough fuel

He checked with a line on top of the engine when turned over fuel was coming out fine. Ok u said high pressure pump line? And will it show codes even if it won't start?I mean doesn't it need to be running to run a scan tool on it?

Ok so it should spray all over then? And it won't if the line is cracked? And where is this line? Is there a website u know of I can get a diagram to show me where it is?
