hi i have a 1996 p38 4.6 HSE range rover ,it was going fine i drove it to my work then when i was leaving it would not start all the lights are on the dash and everything works but there is nothing when i turn the key not even a click from the starter , thought the starter was gone so i put a new one in but still nothing ,got a auto sparkie out and he said it might be the fuse box , so i got another 1 out of a running p38 but still nothing .the battery went flat and once fully charged i had to put in the 4 didget security code but still nothing is happening .

to me it seems that it has immoiblised it self for some reason ,dont know why , but then i might be wrong

any help would be great

many thx
Gary
