O-rings failed on HPOP. I replaced the o-rings and now the engine has to turn over 4 or 5 times before it fires. It is acting like the HPOP is draining and having to be refilled before the engine will fire. Did not have this before replacing the rings. Truck runs fine after it starts.

What I have read suggests the IPR may be failed, though that seems hard to believe considering that the problem started immediately after replacing the rings.

Also looks like the ICP is leaking and in need of replacement.

I appreciate any suggestions.

I have checked the HPOP and it is full. I was heading in the wrong direction. I am thinking that it may be the ICP.
