I have a stanadyne DB pump on a cummins engine in an Onan generator. It has been sitting for several years but only has 36 hours run time on it. Engine will start and run for 3-5 seconds and shut off.It will immediately restart and die. I have temporarily eliminated the shut down system by running 12 volts directly to the fuel shut off solenoid. Fuel is clean, new fuel filter, excellent fuel flow to the injection pump.I have temporarily installed an electric fuel pump to eliminate any problem with the mechanical transfer pump. Fuel return fitting is clean and open,but no return fuel to the tank. Acts as if it is not properly charging the injector pump with an adequate amount of fuel. Any suggestions before I take the pump to a pump shop. Thanks
