Is there oil under the oil filler cap? Then it isn't the pump.

If you have a bad oil pump the bearings in the motor are already bad.
Have a mechanic check it out for an oil leak.
All Honda's need the valves adjusted every 60,000 miles or the valves get tight and the motor won't idle properly and you also have a loss of power.
