My truck takes a long long time to crank up, i noticed that when i was cranking the engine that the oil press gauge was not reading then all of the sudden the gauge started reading and it fired up, Im assuming that the HPOP reservoir

is going dry, no external leaks, so if the res is going dry what would be the fix??

Someone said something about doing a "jack test", does anyone know what this test is??

The oil pressure guage is from the lpop not the hpop. Mine cranks for a few seconds before the guage moves also. Long starts could be the glow plug relay, or injector orings.
