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 M 84
