Strange that BOTH pumps are coming on, as you say the cards should command all four. Something somewhere is giving a ground to pull in the relays. How about the FJCC? I know they don't have power until commanded BUT.....
Anything logged in the CMC?
I take it that the indications are normal prior to flt. with the 'blue' pumps commanded but not on and the green indications when running?
How about swarf down in the card files
