Sometimes loosening the oil filter and give it a short crank on the starter is enough to draw the oil into the pump - this has worked for me a couple times ... Good Luck

It is possibnle that our oil lsystemis air locked and needs to be purged by loosening the oil filer to let it bleed out the air, as Dan noted above. It is also possible that you have a bad drive gear on your oil pump or your camshaft (or whatevr drives the oil pump) isn't turning. Start by trying to bleed out any air then let usknow what happens.

Did you fill the filter with oil before installing?
