no start
 

Well did oil changed, after I did that uvch went bad and missfiring. So I replaced it and did buzz test. Came out all good but it won't start. It tries to and if it does start only for a second before it dies out. I got fuel, and assuming hpop cause they are firing. What could it be? Orings? Bad injectors. Any help is appreciated! Thanks

Any IDM work?

Any oil in fuel filter bowl? Has camshaft sensor been reeplaced with new updated motorcraft?
