crank no start on a 7.3 powerstroke. ran when parked. scanner data shows high pressure oil pump is not making pressure. starting fluid was sprayed into the intake and it didnt start so now im thinking its low compression.
I was going to do a compression test, but getting the valve covers off without pulling the engine looks like a nightmare. so I just spent $550 goy bucks and bought a new re-manufactured hpop and im hoping that does the trick.
