Not sure if it is the same set-up (I haven't looked under a TSI) but in my 92 ESI, I had the same problem. Turned out the plastic clip that connects the wire to the oil pressure sensor had broken off on the bottom. Check and make sure this is still connected as it seemed like a cheaper part and can break easily.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
