2005 6.0 won't start

[zrx1200]

I bought my truck about 2 months ago and love it. I went to go home last night and the engine almost seemed to start after the typical 4 second crank, but didn't. I tried to restart it( it almost seems to sound a little different), but it only cranks. The tach doesn't stay at zero, so it shouldn't be the cam sensor right? I drained the fuel from the lower filter (it looked very clean) and then tried to restart the truck. The filter did refill with fuel. What should I check next? I am desperate to have my truck up and running again.
Thanks!

Welcome to the Org! Does the engine sound like its trying to fire, or is it just turning over?

how cold has it been and how long has it been sitting? could be bad fuel, dead batteries? try the obvious first.

Ditto. And How many miles are on your truck. Check the fuses and small stuff. If its not any of that then you might be looking at a FICM

FICM
Fuel injection Control Module.

Or a HPOP leak.

Thanks for the quick reply. The previous owner had the high pressure hoses replaced about 4,000 miles ago, so I would assume(I know!) that they are good. How can I test the two possible solutions though? As you can see, I'm trying to avoid taking it to my local dealer as I don't have ANY faith in them.
Thanks again,
Keith

I didn't realize I had all the other responses, until after I sent the previous response. Thanks for the welcome, I'm sure I'll learn a lot here. The truck only sat for the 10 hours I was at work. At first it seemed like it was going to start, but after the initial time, it only seems to be cranking. The batteries are only 2 months old, and I filled up yesterday (about 35miles out of town) at a truck stop. I looked at all the fuses inside the truck and they were still solid...like a dumb butt, I didn't check the ones under the hood. Is there an easy way to check the relays?
Hopefully I answered all your questions!

it is impossible to know what is wrong with this truck on a guess, it could be a dozen things , ficm, high pressure oil leak,stc fitting at pump, ipr , etc., you will waste moretime and money trying to guess than you will taking this truck in and get it diagnosed correctly, is this truck not under warranty

SCUFFY828,
I understand that long distance trouble-shooting is difficult, if not impossible. I, as well as many people I know, have had serious issues with our local dealer. For that reason, I'm trying to narrow down the possibilities, at least the ones that a guy at home can tackle. Unfortunately, the truck has 104,000 miles, so it's out of warranty. I'm not sure if I mentioned it, but the high pressure hoses were replaced by a dealer about 3 months ago.
Thanks again,
Keith

I also noticed that the brown plug that plugs into the back of the lower fuel filter housing (according to the pic in the how to change a fuel filter section of this site), isn't plugged into anything on my 05 King Ranch F350 4x4. The place it shows in the picture is just a blind hole on my truck. Is this supposed to be this way?
