Thanks for the schematic... I'll study real close tonight...

Here's what I can report:
1. All electrical bits in their place and turn on key and Both Pumps Run [used to not]
2a. Remove Air Flow Meter Plug - both pumps continue to run.
2b. Jumper Air Flow Meter Plug with Paperclip - both pumps continue to run.
2c. Keep Air Flow Meter Jumpered with Paperclip...
2d. Go to engine bay and remove overboost switch - pumps stop.
3. Replace OB Switch - pumps run
4. Remove Single Relay for OB Switch - pumps stop.
5. Replace Single Relay - pumps run
6. Remove Front FP Relay - One pump stops and other continues.
7. Replace FP Relay - Both Run
8. Remove Rear FP Relay - One pump stops and other continues.

This is where I'm at... I'll look at the diagram and report back. Thanks! Shannon
