00 7.3 won’t start

My 00 excursion with a 7.3 in it started dumping oil around hpop. Replaced all lines and fired it up it ran about 10 mins and died, but I still had leak. Rebuilt hpop gaskets and o rings but am only getting 300 psi of oil pressure. Replaced ipr and then hpop. Checked all glow plug system, but it just cranks won’t fire at all. Not sure where to go now?

When you replace the hpop it takes a while for it to fire off initially. Is the hpop res full? How long did you crank to try to start? Made sure Everything is hooked back up?

Checked everything twice and cranked on it till batteries went dead, charged and cranked on it a 2nd time till batteries went dead again.

This can be an issue when you drain all of that oil out of the hpop, refill the Hpop and check your oil lvl, takes time to get things up to pressure again

Fill the HPOP reservoir and try again with strong batteries. My guess is the LPOP did not fill the reservoir before the batteries went south.

What was the PN on the HPOP gasket? There are early and late versions.
