1989 Land Rover 2500 Diesel
 

I have a Freight Rover van with a 2500 Land Rover diesel engine. I laid
it up for the winter, now she starts and ticks over but wont rev out.
I put in a new oil filter and replaced the lift pump but still cannot get any
revs over tickover. Throttle cable is moving the arm on the injector pump ok.
Ive run out of talent, can anyone help please? Cheers.
