I picked up a kobota G4200 with a diesel engine a couple of years ago. For two years it ran great, put it away for the winter and the following spring I went to start it up, it ran for 10 seconds and died. Turns out it was getting fuel. Checked all the lines fuel ran freely but pump wasn't running. Took the pump out and put 12 volts to it no reaction, so I order new pump. Install new pump turn key pump won't pump, tried jumping directly from the battery to the pump nothing happen. pulled new pump out, put 12 volts directly to pump doesn't do anything. It appears to be a diaphragm pump, does it need a electrical source the pulsate or did I just buy a bad pump.
