John Deere Stanadyne Injection Pump Troubleshooting - You can't use the old method of cracking each injector line to narrow it down because the injector pump doesn't have a pump for each cylinder. It's just a pressure pump. I've got fuel to the injection pump but none to the injectors. I suspect the electric shutoff isn't opening. I've checked current at the plug at the rear of the pump and i get 8. 8 volts. The de10 pump derives all if its injection timing information. The engine quit under no load approximately five minutes after starting it. I have a jd 210le with a stanadyne de10 computer controlled pump. It will crank and run but will stall like you turned he key off. At first i thought it was a fuel problem.
