Hey Glenn,
Hold on a second...
You said you're not getting fuel through the VP44... WHILE CRANKING.
Be aware the lift pump does NOT run while cranking the starter. To activate the lift pump, you need to briefly BUMP the starter... but do not crank... and leave the ignition key on. When you do this, the lift pump will run continuously for about 30 seconds. You should be able to hear it. Just bump the starter, get out of the truck, and listen underneith the truck for the hum of the lift pump motor.
Assuming you do hear the lift pump running, are you sure there's fuel in the tank? Don't rely on the fuel level gauge because many a Dodge Ram owner has been fooled by a failing sending unit which indicates as much as a 1/4-1/2 tank remaining when the tank is actually empty. It happened to me a couple years ago, but I caught it just in time...
One day when I was out running around town I noticed the fuel pressure gauge start to bounce wildly. The fuel level gauge was still showing 1/8 tank remaining but the lift pump was sucking air! I quickly figured out what was going on, pulled into a parking lot, and transferred some fuel from my auxilliary bed tank. Later I installed a new sending unit and this eliminated the problem.
So, if the lift pump is running try adding 5 gallons of fuel to the tank, then bump the starter again and see if the lift pump pushes fuel through the fuel filter and VP44. Hopefully that's all it is.
Good luck,
John L.
