For a short run, jumper fuse 6 to fuse 4 (left side to left side) to run the pumps.

I assume the System relay (in same white case) does kick in with key on. If so, have relay plugged in when trying the jumper.

If it's just the ECU control that's failing, you can back-probe (ie, jam in) a grounded jumper at the Blue/Green wire on 86/2 terminal. Relay plugged in of course.

Hope this isn't too late.
