Fuel Bowl Full No Pressure at Shroeder Valve t444e No Start

1998 t444e in 4700 truck. engine was running great. but truck not in use due to insurance matters. would start in once, twice a week to keep battery charged. started it up while raining one day. found wipers did not work. no power to motor. fuse, relay good. took the fuse box down, and discovered numerous wires were missing part of their insulation or holes poked in them and never covered up.

I thought it best no to mess around back there (behind the fuse box) and run another circuit and switch for the wipers and cover all the exposed wiring very carefully. as I was doing this It was quite a few wires. I would periodically reconnect the battery and start the engine just to make sure I have not effected another circuit. it would start every time. after I got finished and bolted the fuse panel back I turned the key an got nothing no crank at all. but for some reason it would sometimes crank but no start but then soon as I turn the key off and tried again no crank at all . I narrowed that problem down to the tall yellow 2 second time delay crank relay. so I thought the relay was OL when omh reading was taken. so I changed it. before putting in the new one I checked it and it had continuity. put it in it didn.t fix the problem. Checked the new relay again for continuity and there was none. But when I jumpered the start terminal to the load terminal of the crank relay pug in with a fusesable link the starter cranks the engine every time I also chanced the ignition switch for good measures

Now I have a crank no start problem. My fuel filter bowl is full of fuel. I have no fuel pressure at the shreoder valve next to the bowl. I removed the icp plug it had some oil on the connector I heard that's not a good sign. I tried to crank it with the plug out to see if will go into default and start. that didn't work. I pulled the icp sensor and cranked it then to see if the oil pump was working ok and a lot of oil shot out when cranking. can it be the ipr or could I have fouled up something electrically that is affecting my fuel system. Engine was starting and running fine until I started covering exposed wire and running a new wiper circuit. what could I check next?
