hallo from italy, scuse me for delay in the replay. I solved in "home made way" I found that short circuit wich blown the fuse was on the cable that gave 12V to the diesel elecrtric valve on the pump. made another connection bypassing original cable from fuse box to diesel 12v valve and cut the original cable to electrovalveDid you ever resolve the short? I'm having this same problem on my 1992 HDJ80 (European model left hand drive) and am over 17 hours in diagnosis time with my garage and they cannot find a wire that is shorting. I also don't have the 1990-1992 EWD, as cannot find a digital version anywhere on here or other LC sites, only the 1996 EWD, which according to my garage is different, as there were upgrades made by Toyota on post 1992 model LCs.
