I'm having the similar problem with my 92 disco, had a wiring issue a yr ago when all the lights went off, had it fixed and since then it's starting very intermitantly!! It does that clicking thing for a while then slurts and starts. Sometimes it just makes no sound and then if I hold the key on it starts 10 secs later - bloody wierd. Strange thing is I left it into Garage for a week and it started every time for them while they were servicing it. If u have any joy could u let me know what advice u got - good luck.
