fuel problems on a cat D5N

[Scotty Scott]

My D5N slowly increases RPMs the highest it gets to is 2071 when you press the decelerator and release it it will only regain to the 1300's i have replaced both of the fuel filters and the rubber lines from the tank to the first filter and checked the orfice in the return line. What could my problem be?

I tagged a mod for you. I'm sure they can move it no problem.

I'm sure they can move it no problem.

It took like, seven clicks of the mouse. You have no idea how taxing that can be at this time of day....

Any warning lights or faults?

That's a heui engine and it could be lots of things. Heui pump not making correct actuation pressure, IAP, boost, atmospheric pressure or oil temp sensors giving a bad reading. You need someone with et to look at it or at least some sort of scanner that can read some of the parameters.

That tractor is equipped with CMS. Are there any Active Diagnostic Codes (SERV CODE icon on RH side of screen permantently lit) showing on it..?
