Help me fix my ford backhoe

kevin saunders My 1989 ford 555c backhoe will start and idle fine but no throttle response.Has anyone had similar problem?
thepumpguysc Diesel, CAV pump??
Sounds like a stuck metering valve.
Hold the throttle wide open, push and pull the stop several, 5,6,7 times quickly,and see if that did any good..
IF NOT sounds like your going to have to open her-up.

sixbales Hey pumpguy, I need some of your expertise. I copied this note from another forum regarding a CAV pump:

What is the part that is bolted to the bottom of the main housing for, neighbor removed the jam nut and screw and said a needle shaped pin came out he reinstalled it now the tractor won't start. He thought that was a bleeder screw,he has a good flow of fuel no air bubbles, but can't get any to the injectors , the tractor is a 6600 with cav fuel system

thepumpguysc SB, That would be the "manual" cold start advance mechanism..
When the pin came out the seat, ball and spring were lost..
ITS A VERY important part of the fuel system.
See if you can get the pump #, I'll see if I have one..

sixbales Thanks for your help pumpguy.
