Angry fuel and Electrical trouble's STILL 190E 1991

OK folks I have done more research on this car, today I took one of my fuel pressure gage's and checked to see what the fuel pumps are putting out. Direct from pimps to the fuel distributor I had 190 pounds over an hour it drifted down to approximately 150lbs. I also had an issue with two apparent leaks at that high pressure the photos show the hose to pipe connection at both the distribution line and the line at the fender leading on to the fuel inlet. I then checked the vacuum line at the fuel pressure regulator found it held no vacuum unless I pressed down on the hose connection, though I do not think that it is to much to be concerned about, as it gets minimal vacuum pull from its connection at the engine vent tube.
I pulled the plug for the crank shaft position sensor and had a reading of 825 ohm's went on to check more fuel items and lost signal to my fuel pumps again. this was what started the entire search, checked ovp and fuses they are good. I have not had the fuel relay out this time, but the last time the pumps started working after I jumped 1&2 poles. kind of at my ropes end here may have to take another day and just continue reading post's Bad when you get one end working and the other end unravels!
