TD, were you running the pumps with engine running or not running? If engine not running, then all electrical is off the battery and a bad battery could mean low voltage and, thus, no pumps. If engine running, then alternator dominates the electrical system (14V, 70-100A).
Assuming the pumps are OK, then depending on your answer you might have a bad battery (or just a run-down battery) or a bad alternator.
x2 on Jake's comment. My sound system was overwhelming alternator capacity, so the current draw toasted the alternator wires (esp that little bitty black ground). Everything looked OK until I jiggled the ground and it LITERALLY crumbled in my hands. Rebuilt alternator with 120A kit, upgraded the cables, and all good since.
