Won't stay running

[tjcausey]

I have a 95 7.3 that had block sealer added to the oil. The truck won't stay running even after I flushed the oil, cleaned the pump and screen and changed the sending unit. What else can I do. It will start and read pressure for a few min, then it looses pressure and shuts down.

seems like oil is being blocked somewhere but it seems like you covered everywhere. I would go through everything again. clean out the screen, replace filter, clean out HPO reservior at the pump
