Stop blindly changing parts and diagnose the problem. Get a set of Helm's manuals off the auction site or a Haynes manual and follow the test procedures.

You seem to be asking for help but you didn't provide even information for anyone to even make a guess. You might want to provide some basic information starting with what engine / transmission that you are working with.

Parts store parts for these trucks are notorious for unreliable quality. You may be better off putting the originals back in place.

What made you start changing the fuel system parts? Did you rule out the ignition system first? Did you check fuel pressure before swapping parts?

1996 eddie bower f150 , 5.0 automatic trans ,
started out by checking for codes ,there were none, then if course I checked the igniton system ,and spark there was work to allcthe plugs , wet ahead and changed the plugs while I was doing the spark test. Then I checked for fuel pressure, oh no pressure , changed the filter as I have had that issue before on another truck. And the pressure was still not there, changed the pump, bothe tanks,( as I live in a remote area and figure do it once now and no worries later) still no star so I changed out the tank control valve still nothing . Found loose ground at the tank fixed it got pressure back , (yeah), truck started ran for a mi test then died.
this the issue now, starts run a short time and stops.
that is why I'm asking for ideas what to check now.
