I have never worked with the full flow oil pump, but with a blown filter,
I would suspect something in the oil pressure relief system in the pump.
After that, go to the factory pressure relief valve.
Something is blocking the oil from getting out of the pump.

If you are getting no oil light with a new switch, try grounding the wire
to the engine block and see if you have a light then. if you do, then your
new switch is bad. The oil pressure switch just grounds the light wire
when there is no oil pressure.
