Did you take oil line off and see if you were getting oil to gauge?

You will need to drop the oil pan and check the Pump and while you have it off, you should check the bearings on the Crankshaft as well.
What is the oil like right now, have you got the correct grade in there, are there any unusual noises coming from the engine now. No pressure is not good. It could be that the Pump is not turning due to something shearing, drop pump and take it apart to measure wear at the end of the lobes on the "gears", should be no more than .010", if the wear is approaching that anyway, it needs changing, you can check components while you do all this. The Radiator needs cleaning out often 2 or 3 times a day when it is dusty and there is vegetation blowing around, the same applies to the Air Cleaner as well. Use a hose from the engine side to the front and make sure that you get all over the radiator especially into the corners. Use a light at the engine side and look in from the front so you can see just where there is any blockage. If you allow the engine to overheat like this there is a big danger that the Cylinder Block or the Head will fail.If you need help, just ask..John(UK)...fergusontractors@hotmail.com

Make sure the oil pick up tube is not cracked or leaking and that the presure relief valve is not stuck open. Is the oil pump drive gear pinned to the pump drive shaft.

Then it looks like either the pump is worn or the bearings on the crank....but check the pump for wear...John(UK)...fergusontractors@hotmail.com

Was there a piston at the top of the spring in the releif valve? Was the spring the correct one? It can be shimmed to providea higher relief pressure.When you say "it affected nothig" what do you mean?
