You guys are so slow!
So, I came up with a test. I wasted a $61.00 oil and filter change to weed out a cloggged fillter, and fired it up. Still no pressure reading. Next I loosened the fitting at the case where the sender goes and oil trickles out, but thats about it. Not even enough pressure to squirt oil. I cut the old filter in 1/2 but it looked clean, but I did get some (very little) brass when I removed the sender.
