1989 Voyager help wanted!

What are the error codes showing up?
You should be able to just turn the key to "ON" without starting and hear the fuel pump try to run. If you can't hear while in vehicle have someone help as you listen at the filler tube.
Went through 3 fuel pump replacements between two owners (requires draining/pulling down the tank) before finding the lead running to the fuel pump on our '88 had corroded internally. I don't know that it was a common problem with these.
