2009 maxxforce dt466 no start

i got a 2009 ih 4400 with the maxxforce dt466 it turns over fine but will not start i checked the fuel filter it was clean but when i put fuel into the filter housing it will not fill up it just goes rite thru i put the filter back in and then pumped up the primer pump and hooked up my fuel pressure gauge it will prime up to about 50 psi and then go rite back down to 0 psi but when i start turning over the engine it will slowly go up to 60 psi and wont start the pressure then drops to 0 psi when i try to start it it will barley run for a few seconds but wont crank i just put in a new lift pump that mounts to the hpop this engine does not have the electric pump i bought this truck at auction with it not running to start with any ideal what to look for ?

 

thanks for the info i have been looking everywhere to find any info i can about a fix. i did have the truck scanned and there was no codes found did a buzz test and some other test my buddy has a scanner he could only figure it has a oil leak some were under the valve cover like the icp sensor so i had it towed to my home before i started to pull the valve cover i checked the fuel filter it all looked good when i went to put the filter back in i filled up the filter housing and it would just drain back down i put over a gallon in it .it still would not hold the fuel so i tryed to watch the filter housing when turning over the engine it would fill up real slow so i thought it may be a bad lift pump so i got a new one and put it on it will fill the filter housing up faster but it still would not hold fuel so i pulled the return line at the fuel tank and blocked it when i did that it would hold the fuel then i checked the fuel pressure again it went up to 60 psi and held for a while longer but still would slowly go down so i got some help to turn over the engine when i pushed the primer button in when trying to start it . .the fuel pressure jumped up to almost 80 psi but the truck still would not start so hooked back up the return line and tryed to start it again while watching the pressure gauge it would start out at 0 psi and it would slowly start to go up to it would start but barley try to run but just will not run

 

when cranking the rpm gauge will move a little and the oil pressure will come up to about 40 when cranking it was scanned and found no codes was told it may be a leak under the valve cover the scanner showed a leak some where

 

i looked today and watched the rpm gauge and oil pressure gauge didnt not move at all when i was turning it over stopped for a few seconds and turned it over for about 20 seconds the oil pressure came up to 40 psi and the rpms were about 300 had the fuel gauge hooked up and it read almost 60 psi but still no start

 

here are pics of the filter housing on my 2009 dt466 i dont see a allen head screw i do see the filter regulator with the spring also there is a check valve where the return line goes to its the only thing that i could see that would make the fuel go down real fast it does it blocks the fuel line from backing up into the filter housing too i dont know how it can come out to be replaced

 

i got the truck to fire off today i undid the air filter intake and removed the egr crossover pipe its smoking pretty good and has a loud tapping noise there is no exhaust coming out at the tailpipe so something is clogged up good it will not get over 1500rpm but it runs i did put a new ipr and lift pump and fuel pump regulator was replaced too when it first started it would barely idle thats when i undid the egr crossover pipe it ran ok but still not running rite its smoking like a freight train
