89 club wagon van dual tanks, neither gas gauge is working. what could be the issue

Probably the gauge on the dash. It is unlikely both sending units failed at the same time, but it could also be a wiring problem or a bad selector switch if equipped.

1991 Ford Econoline Problem Starting

It may not have anything to do with the tank switch. It sounds like the check valve in the pump has failed. The valve prevents fuel pressure from draining back into the tank.

I was driving and the van just died. it still turns over just doesn't fire. i'm guessing it lost spark or gas. nothing happened, no warning signs. it just died. fuel pump is 1.5 years old. whats a fast...

Have someone turn the key on while you have you ear close to the fuel tank. You should hear a 1-3 second whirr as the pump builds up pressure. If no sound you can tap on the tank with a rubber or dead blow hammer to see if the pump is stuck. This trick will only work so many times before complete failure! Fords also had a fuel pump shut off switch, after Pintos started blowing up. Most cars had them in the trunk under the plastic covers. I'm not sure on the vans. Look for a small black box with 2 wires near the tank on the inside of the van. You can cut out the switch and tie the wires together with a wire nut and black tape or shrink tube to bypass the switch.

When the 1990 Ford van is switched to the front gas tank it will run for a few miles and then acts like it is out of gas. When I switch to the rear tank no problems.

When you switch tanks can you see what the correct amount of gas is in the that forward tank? Can you verify that the fuel-pump inside the forward tank is coming on? A common problem for fords are the selector switch units. But you want to make sure you narrow it down enough so you don't buy the wrong part. Let me know how it is going.
