No Fuel from injector pump

Hello, relatively new to the diesel/Cummins world. I have a 1994 Dodge Ram 2500 with the 12V 5.9L cummins. Recently I found out more than half of my fuel tank was full of water. I disconnected all fuel lines from motor all the way back to the tank and drained the tank completely. I refueled the tank with all new diesel, I have bled all the air up to the injector pump. I had the fuel lines from injector pump to the injectors disconnected, open the banjo bolt on the front side of the injector pump. I got fuel out of the back two of the injector pump, but cannot get fuel from the other four. I have checked the fuel shutoff solenoid to ensure it was operating correctly, and it is. I'm not too sure what to do next. Any ideas or information will be greatly appreciated.

Thank you!

It takes A LOT of bleeding to get the air out. You'd be surprised. I reworked my fuel system and I was experiencing the same issues. But I knew there were no other possible explanations, so I just kept pumping the lp. If not, check your heater for leaks.

It took no time at all to bleed my 98, all new fuel lines, filters and IP.

Pushed the primer until fuel shot out of the fuel filter bleed bolt roughly a hundred or so pumps. Gave it a few more pumps untill the overflow valve popped. Cracked 3 injectors and after 2 seconds of cranking the truck tried to start. Tightened the Injectors and fired up like it would on a normal day.

I?ve been doing everything I can think of to get all the air out. I went from fuel tank all the way to the pump. I cracked open the banjo bolt on back top left corner and got fuel, but cracked the delivery nozzles at the injector line nut and nothing. Bone dry. I replaced the actual delivery valves thinking that?d be the issue... I?m running out of ideas here.
