Certainly could be. To check this, make a little jumper wire with a male
end on each side. Take out the fuel pump relay and jump the two wires (I
forget the numbers on them) but it is the two wires that are in the middle
of each side (four sides, the ones that are not on the corners of the
relay), and they are perpendicular to each other. When you jump these
wires, the pump will run continuously. If the van starts now with no
problem, the relay is the source of the problem. If it does not start, then
I would start looking at the charcoal canister. If it is clogged, the tank
cannot breath, turning the tank into a huge vacuum. The pump pumps, but
cannot pump fuel because of the vacuum.
When you jump the wires, remember that the jump will run continuously with
the key on. If it does not start, immediately turn off the key or you will
fry your pump.
Also, the more technical way to check this is with a voltage tester at the
pump when you turn the key on. Easy to do with two people (one turning the
key on, the other checkng the tester). In the absence of either a tester or
a helper, use the first method.

Wait a minute! It is probably NOT the fuel pump! But instead the fuel
pump relay (located in a black box above the coil) is you likely
culprit. If you turn on the ignition and don't hear the
click->sigh, just sit there quitely and wait. Once the relay get warm
enough it will make contact and all will be happy. In cold weather i make
it a habit of turning on my ignition for about 10 minutes before i fire
her up. THis also helps to warm up the battery so you'll have more juice
for the starter. I only do this for the first start of the day- when
running errands it is fine.
Home this helps
