Ford Ranger / B-Series :: 1990 - Extremely High Oil Pressure / Heavy Smell Of Burning Oil

I own a 1990 Ford Ranger, 2.3 EFI with an 8 Plug setup and 2WD. It uses a dual-coil system an not a distributor if that means anything here.

Okay, so for the last week I have been experiencing extremely high oil pressures. My gauge would read almost as high as the "H" mark. The smell of burning oil was heavy in the cab from the vents. I took it easy, made sure my oil level was good and I had enough oil, the truck drove rough, but drove decent.

Yesterday, I got done sliding in some mud (not crazy bouncing or anything, just sliding). I stopped at a stop sign, turned around and hit the gas, and the truck died. I thought there were other issues not related to oil, however I noticed that the oil gauge now read about an inch left of the "L"ow mark. If I turned the key, to the "ON" position, the gauge pushed the needle to above the left gauge itself pointing towards about the "8 oclock" area.

Now, my truck will not start. It cranks and cranks and cranks with no start. I called a bunch of mechanics and none of them knew what I should do. AutoZone did not know what do, no one did. Some people said that the oil pump itself had gone out and that would cause the truck not to start and would cause gauge issue. Others said that it might be as small as the Oil Pressure Switch. Firstly, I bought a new Pressure Switch. Have not installed it because I cannot find the damn thing.

Where the switch OFFICIALLY is. I have read on Google that it is on the passenger side, at the rear end of the cylinder head. Other posts say it is by the oil filter...
