i have a 94.5 powerstroke and i was cruising down the road today and my truck start lightly making a knocking noise. It occured right after a climbed a hill on the highway and got 1/8 mile from where it started making noises and pulled over and shut it off. I noticed before i shut it off i had lost oil pressure. So when i started it to get on a trailer it started knocking....please help I need to get running

Check the main oil level. If your injector O-rings went bad, you might have used the oil via it getting into the fuel system. If that is the case you may be OK after a simple o-ring change. Cheers!
