Ok so I put a 1983 Mercedes 300SD drive train into my Jeep:

The problem....No power!!! When it was in the car it had power could cruise all day at 70mph.

First the truck weight about = to the car (estimate less then 4,000lbs)
Gear ratio 4.11 with 32 inch tires should turn 2,700rpm at 62.5mph (100km/h)

here is the problem I have no power at all. I can get 50mph on flats and no power on hills.

It has the electronic automatic... I realized I do not have the electronic pressure control rigged up (think I left the part on the car that was scrapped due to rust).

So any ideas on how to rig the pressure control or set to full throttle since that seems safer then no throttle setting.

what other issues could I have?

I have a 2-4lbs lift pump at the tank to the injector it goes through new filters (2 before lift pump and stock filters at motor all new). Motor starts no problem with or without glow plugs (factory relay wired in). Engine burns clean no black smoke.

Since it all worked in the car I want to get back to it running that way before I adjust the injector pump or anything.

I am now living in the truck in the bush collecting field data for my graduate studies so it will be a week or so till I can check here. but help is needed.

Basically I was going up 6-7% grade (10mile climb in low range on the transfer case engine, no power 10mph and temperature started climbing from 190 to 220 so I shut it down and got towed (550.00 dollars later). Now I am in the bush but need to get it running....Help please!!

Thanks David
