200tdi Starting At Full Rev

So I am in the final stages of my Disco 200Tdi swap into my ex-mod 90. After getting most of the kinks worked out I started the engine to get some motivation to finish. It has been a slow process to put it mildly.
So after replacing a bad lift pump the engine fired up but runs at full rev. It does turn off with the key and the breather is not connected so I don't think it is running away. I have read of IP's causing this if not properly stored.
Has anyone had experience with this and is there a way to fix it short of pulling the pump and having it rebuilt?

Thanks,
Ed

P.S.
I replaced the following prior to install:
Timing Belt
Water Pump
Belts and Hoses including oil lines
Fuel Filter
Rad and IC

Random shot at this...... Is your throttle cable hooked up? Have you tried to move the throttle by hand on the IP? Any resistance or feel to it?

Probably hooked up, and far too tight.

I would try feeding a diesel fuel conditioner straight in, then let it sit. Then try again the next day. As above, cycle the throttle lever. Maybe whack the pump body with a hammer.....

Ed,

I'm in Norwich. I'd love to come by and see your install. Is your 90 LHD?

Started both ways with the throttle cable off and on. Same result. I will try the above suggestions. The hammer is my favorite land rover specific tool.
Neil, yes lhd. Bring cash when I'm at work and my wife will sell it to you, heck she might even pay you to make it go away.

Throttle moves there is no change in revs. There is resistance via the spring.

I think we found where you need to look. Is the screw tight that holds the throttle "bracket" onto the shaft coming out of the pump? Does the screw rotate with the bracket when you move the bracket?

Ed, it is possible that the IP was taken apart at one time and the throttle lever replaced and if memory serves, was clocked in the wrong position.

This is a "shot in the dark", but have seen this on other diesels with a VM IP.

Another possible cause is someone cranked the fuel in on the fuel adjustment screw.

Ha ha, You found Briggs' new signature line.
Actually I'm at work now so ... I'll check when I get home.
I don't think the pump was rebuilt, from the looks of things the motor was packed up and shipped as is.

Yes the screw on top of the throttle rotates with the throttle. There is definately resistance too. A quick search brings up checking the diaphragm. How would I check for a "wide open" fuel rack?
Thanks,
Ed

Pull your pump and send it to a shop to clean and reseal. I did that with a pump this summer and cost was around $250.
