7.3 diesel no start
[/PHP]i have a 1996 ford powerstroke was running fine tell i noticed a oil leak under truck so i pulled it apart and noticed the injection pump leaking so i ended up resealing it and then while i hade it apart i replace d all the o orings in the fuel filter housing and rebuilt the regulator and fully cleaned everythang in valley down to a t then went ahead a reassambled the top end then tried to start cranked no prob but no start so i read code nothin came up also had no smoke so i was thinking fuel or oil injection i also had done a full oil flush while i had it done to clean the system so i was reading that u have to prime system so i took the sensor off filled it with oil and when i was doing this one of my friends kinda messed up and took oil lines off all springs inside the oil line fittings i have been lookn for a diagram on how they sit in the fittings\pump and if there is a check ball in one of them or just spring?
I had installed it the whay i thought was right and no start but i sprayed diesel in the intake and would run for a second thats is did a shrader valve test and was getting 5 when built up so i thought fuelpump cuz it was low so i replaced fuel pump and checked hhop everything semed ok but whats got me wondering the truck ran fine when i pulled it apart so how do things go bad when they are not being used batt fully charged also replaced glow plug relay and then itwas also poping the fuel pump fuse 22 i think its 22 but any way so i needed to clean up the wires ny way so i did and loomed it then re installed now not poping fuse but stilll no run i also went ahead replaced fuel lines and primed it up to pump and made sure it was pumping it was just no fuel out of the black lines comin out of the front of head and the oil was pumping oil just want to reinstall the lines and spings correct to start then im gana have to get 1000 psi gauge do not have one also i had no codes ?
does any one think they could give me a hand im machanicaly inclined on gas motors just diesels are new to me kyle? thanks 1996 ford powerstroke 4dr long bed 4X4

also 12.0 at batt tach does move when cranking has endge tunner oil in res is full and new also if there is a small leak in line would it cause fuel nt to flow correctly cause its dual tank one manuel pump in valley new also new vacume pump all fuses good no codes wait to start stays on for 10 15 sec then goes off cranks good speed cleaned all fuel lines does it have to be primed ? i primed it with my shop vac sucked fuelup hoses to make sure had fuel not cloged also filled fuel bowel and replaced heater element and cleaned all of it no leaks new filter oil and fuel

the oil is full so the hhop is not a oil injecter its under the resavoir that has a gear bolted to in 2 lines come off goin to my block that have oil comin out at high pressure

in every book my truck has a high pressure oil pump i may be wrong i just thought that it is a h igh presure pump that sends oil to injecters to open then up to deliver fuel down each piston
