6.0 Crank but no start
 

I have a 2003 F350 SRW extended cab with a 6.0. I've had just about everything you can imagine replaced on this 6.0. Less than a month after getting 5k worth of work done on it (new oil cooler, new filter housing, new turbo, injectors "checked") it won't start. Started off at the advice of the mechanic that just had it, changing both filters. Still no start. Had a second mechanic look at it and he's convinced it's a fuel problem. Upper filter housing is draining...i.e.I can turn the key, watch it fill, then watch for about a minute and it will completely empty out. From what I've read everything is pointing to an open injector OR FICM. I'm really getting tired (by that I mean my wife is getting tired) of pouring money into this truck. I might add it has an aftermarket EGR that was installed by the previous owner and the FICM was tested about a week ago and was showing 48V.....I watched the mechanic test it.....I'm stumped...any help would be much appreciated....oh, and 2 different scanners show zero things wrong with it..i.e. no codes
