Do you have three lights in a row, top one red that says stop engine, middle, yellow says check engine, bottom yellow, says wait to start? In my machine next to those three lights is a big silver button I think it is labeled engine diagnostics. After an incident where the check engine light comes on you can shut the machine and engine off, turn the key to start position and push that silver button down and hold it there. As I recall the red light comes on then the yellow light starts to flash. count how many times it flashes. there will be a pause then the light will flash again, count this number, another pause and count the final number of flashes. I have learned that code 4-5-6 is the fuel pressure sensor code. Code 2-7-5 is the front selonoid. There isn't a thing about this in the book and my MF dealer couldn't help either. There was one cummins guy at a truck repair place that walked me through this on the phone. The code that came up was 2-7-5. this guy couldn't come out for a week or so. It was another truck mechanic that came out and hooked up a laptop to get the same code but the software ran him through some troubleshooting and of course I ended up replacing the charge pump and the injection pump.

I was down for week waiting for my parts and ran about three days at half power before that. I have yet to get into the corn and have 500 acres ahead of me.

Good Luck!
