Stuck! '03 7.3 won't start

Cant get Truck to run. Went outside one morning, wouldnt start, ran fine up until that point. First thing i noticed was fuel pump on frame was making a loud odd sound, took off fuel filter on top of engine, turned key was getting almost no fuel at all replaced pump, continued to bleed air out now i get fuel.
Still wont start, changed cps still nothing, about 8 months ago i replaced all glowplugs and had a problem with the valve cover wiring harness, fixed all that. Glow Plug Relay is fine checked that. It cranks and cranks but will not start, any ideas or suggestions would be greatly appreciated....Thanks

You got a WTS light when you first roll-on the key?

Getting any smoke when trying to start? What is the current fuel level? How is the condition of batteries and connections? Any tuner or chip on board?

Where did you get the CPS from, and you did plug it back in after changing?
Fuel pump noise seems and lack of fuel seems to be start of issue.

3/4 tank of good fuel and good flow(could confirm by opening drain valve with key on), batteries and connections in great condition(would charge or have load tested), oil levels good and plugged in, no check engine light(?)

You could open the top plug on the HPOP and see how far down the oil level is. It may be down some from extended cranking with no start. Should be within 1/2" I think. You could also disconnect the ICP sensor on drivers side head and try to start.

Hopefully others will chime in. Good luck.

check all your fuses, especially the fuel bowl heater fuse. I had this happen on my 99 randomly. I have to unplug the fuel bowl heater (on the fuel bowl) and then replace the fuse. Started right up.
