We are getting the error code E-1728-03 with a message about the fuel rail pressure being exceeded, followed by the engine derating. So far we have changed all fuel filters, cleaned air filter, and checked fuel flow out of tank. There is a lift pump on this rig. Happens when the engine load gets high. There is no chip/tune on the motor. Has anyone had this issue, or have any ideas about whats causing it? We have to restart the combine to resolve the issue and its happening relatively frequently.

Thanks

Have had same problem on an 8070, the fault needs to be cleared by your dealer with E.A.S.Y (engine software) other wise it will keep coming back, while in E.A.S.Y monitor the rail pressure while working machine to see if the rail relief is cracking or if the sensor is faulty, there have been issues with the wiring going into the head to the sensor so it may be that, Good Luck!!

Had that happen too. It was a piece of plastic in the fuel pank that plugged the fuel intake. I would open the feed hose from the tank and stick a rod up to free the flow and it would be fine until the piece came back. I then decided to drain the tank to remove the piece but it was to big to come out the botom. So I welded a pipe to the tank bottom fitting so the obstruction could not plug the outlet again. It has worked very wel, no problem since.

I know this is an old thread but we are having the exact same issue with a CX8080. Do you recall what the issue was? So far have change the fuel pressure sensor and the rail pressure relief valve. No luck.

Thanks

Plastic chunk in the fuel tank iirc. We added stems with holes to the fuel inlet line to prevent it.

Or a bad wiring harness to the injectors. That was on one machine. Haven't done the rest.

It's almost certainly a piece of plastic flashing from the tank molding if there's no schmoo blocking the hole. It plugs it off/ code goes intermittently?

Add a stem to the fuel inlet is the fix. I think we added 6 inches and they had holes drilled into them.

Ok thank you.
