air

The only thing you can do is spin it over in short bursts giving the starter time to cool until the base oil pressure comes up then shortly after that the hp oil will come up. Did you remove the gp's and spin the engine to get the fuel and oil out of the cyls?

The reservor is right above the water pump and right in front of your fuel filter housing on the front of the engine.

The hpop res. is full. But, no start, not even a spit. I checked the main connection, that looks good. I also checked the plug at the valve covers that also looks good.

no start

Normally, 15-20 seconds cranking will bleed any air out of the high pres. oil system, allowing the engine to start. After that, a decent road test will take care of the rest. If your oil pressure gauge is coming up while cranking and you still have a no start, you may have a leak in the high pres. system. Make sure all injector connectors are seated and clipped and the under valve cover connectors are connected. If all is ok, make sure the injecor o-rings were properly installed and lubed before the injector was installed. Because the high pres. oil is fed through the head and not an oil rail like the 6.0, a torn or improperly installed o-ring can give you enough of an oil leak to not reach the 500 psi. necessary to start the engine. Also make sure the injector was properly torqued.

What is the torque spec. on the injectors? All injectors have new o-rings and lubed. But anything is possible to go wrong.
