I recently purchased a 1 owner Silhouette. The van was great for the first 2 months, until it died 2 weeks ago in the middle of the road. After checking to see if the fuel pump had power, we determined that the pump was getting power, but wasn't working. We replaced the pump. Now, the pump isn't getting power, the power sliding door isn't working, the blinkers and back up lights are not working. We traced wiring and tested for power, blown fuses, links, and breakers to no avail. We have power from the electrical system, from the key, but not at the pump, door, etc. Any ideas?

Did you check 20 amp inline fuse, behind right headlamp? Not only check the fuse, use a voltage tester on the fuse circuit. Even if the fuse is good, if no voltage on the circuit, the circuit is dead. The circuit goes hot when you turn on the key. Also, there should be a fuel pump test connector, behind battery, red wire with electrical connector, nothing plugged into it. If you use a jumper wire, with inline fuse, from B+ to connector, the pump should run. You don't need to use the key. At the pump connector, gray wire is voltage for pump motor, black wire is ground.
