I just picked this up last weekend.
1997 Discovery 1 SD in Epsom Green
Non of the gauges work
It shows 136k on the clock
It will run if you feed it with starting fluid but misses badly once you get it running and takes decent throttle to keep it running
I am getting fuel to the rail so I think the injectors are the problem.
It looks like the amp has been bypassed and there are some cut wires I am not sure what they go to.
Hoping to get it running and road worthy.

 

Good luck with it!

 

Thanks I found a plate under the seat looks like it may have been sitting since 2009
