94 6.5 diesel won't start

[Jorge6.5]

I'd hate to see what kind of crap is growing in that 5-6 year old diesel fuel.

92 or 94 is very important to know the exact year; 94 is first year for electronic control of the injection instead of mechanical...very different setup and a whole different host of problems.

Exactly. If we know more about the truck, we can help much better.

Old post but getting back to it. Fuel is only like 6 months to a year old and has been started periodically liked at the truck it's a 94 has fuel up in filter replaced fuel pump relay and no help there. Truck just cranks. Where should I go from here

There's a valve on top of the fuel filter, open it then turn on the key. If the lift pump works it should blow fuel.

If you are sure there's fuel at the filter try cracking a fuel line at the injector. 19mm wrench. Crack it open and turn it over. This will push air out of the system. Close it if it starts.
