long story short, i was driving and it was running fine, out of no where it started running rough and died, wouldn't restart for a few minutes then restarted. drove it about 30 feet, shut off and wouldn't start again.
not sure if it matters but the night before this happened, i was using it to pull a stuck vehicle out of sand. the truck was beat on quite a bit that night but it's an old work truck i barely use. it drove 30 miles when we were done and didn't skip a beat.
the truck has been down for almost a year and i haven't really had time to mess with it.

i've checked fuel pressure when it went down originally and it was up to spec (can't remember what it read , it's been so long)
spark plugs are new
the asd relay is good.
it has zero codes.
replaced crank position sensor
replaced cap, rotor and ignition coil (didn't do wires yet but the old ones looked alright)

the truck won't even start if i give it ether, it sounds like it wants to hit but just will not.
i'm completely stumped at this point.

 

Have you verified spark at the plug, by either pulling one out or using an inline tester?

 

When it doesn't start you need to see if it's getting spark. A timing light on the coil wire is a good way to see if it's getting consistent spark. If you can put it on a high end scanner you can see if it's not getting a consistent signal from either the cam or crank sensor. As for fuel pressure you should see 49 psi as soon as you turn the key to on.
