Hi, I have a Kubota SVL95-S2 and engine will not start unless I unplugged the rail pressure sensor and get code E9301. If I plugged back in it will only crank and no start and no code. This engine has what it looks like a 2-wire coil on top of the fuel supply pump don't know if that's the SCV. When I unplugged the fuel rail sensor it starts and after a couple seconds runs rough which is understandable. My question is, could it be a bad fuel supply pump?
Thanks
Thanks
