790elc deere I think its a 93 modle
Does it have the Linde hydraulics or the Hitachi?
It has Hitachi
Make sure it's not a fuel supply issue or a stopped up filter. If you have the square glass AR50041 fuel filter see if it's getting air bubbles in it or if you have the round final filter break the bleed screw loose with engine running and operating the hydraulics and see if you have fuel pressure on it. The elbow in the bottom of the tank could be stopped up. There are a lot of variables in a 790E having slow hydraulics. The electronics will only allow the pumps to pull the engine down 200rpms or so and a horsepower loss is the easiest thing to rule out first.
