truck has been sitting four six months cranks but has no fuel pressure fuses are good not sure where the fuel pump relay is any help

 

Check for power at key on at the inertia switch in the passenger kick panel.
There will only be power momentarily after the key is switched on so set up your meter so you can see it and turn the key at the same time or get someone to turn the key for you.
If you get 12V out of the inertia switch it is time to swap the fuel pump.

 

smack the tank with a 2x4. Seriously. If the battery was dead and you tried to crank it, the brushes and commutator in the fuel pump may have arced and are not making contact.

 

Unfortunately, Ford changed around the location of fuse panels and relay locations quite a bit between years and models. On some, the relay is behind the radio, to the left of the turn signal flasher module. On others, the relay is an integral part of the under dash fuse block and is not field replaceable.

As mentioned above, check the intertia switch behind the passenger side kick panel. Check for power before and after the switch. If there's no power going to the switch, then it points toward the relay. If there is power coming out of the switch, then it points toward the fuel pump.

 

The 2000 has the serviceable relay behind the radio. Off the top of my head, it was 02 or 03 when they went to the non-serviceable (easily) relay in the CJB.
