Since all of your timers are having problems I would check the power connections to the timer box and at the battery. If they are loose or corroded you might be getting 12v with enough current to run the timers but not enough current to run the pumps. Tighten all the screws in the timer box and make sure the battery cables are clean / tightened.

If that looks OK, then you can direct power the pump motors from the battery and see if they run. If all those run and you're still having problems send them to me and I'll reprogram the the timers.
