With the power off I would recommend re-seating all cables. alot of time the pins don't make good contact. If that fixes the issue that normally a red flag... meaning it will pop up again unless you fix the cable thats causing the issue.. I would start by reseating the cable on the power supply board (the one with the big heat sink in the upper right hand corner) there are two cables on the side of the board. the smaller one on the bottom is the selector for which solenoid gets activated. Start there... also check all fuses with power off and out of circuit with a continutiy tester.. (pardon spelling issues... typing in the dark)
