Update:

Had a couple of mates round last night to help me with a few bits and pieces, one is an electronics tech. so he tackled some wiring, but did say it'll take him a few sessions to sort it all out. He looked at the car and said "where do you want me to start"
I decided the thing that was pissing me off the most was that the fuel pump was wired off the lights, so that's what he got cracking with.
Fuel pump is now wired into the car loom again and looks factory, but with the cutout switch removed as i was unsure if this was working or not (might put it back in later). Anyway tested the whole thing before he wired it up, got rid of the old wiring, and fixed it, connected it back up and now it doesn't get anything...

I'm not bothered though as it's all progress as far as I'm concerned. We spent the remaining time cheking over the other wiring and think we've found out the cause so i'll hopefully get that sorted this week.

NOW, the better bit, my other mate who's a mechanic was round helping me strip the car of all the crap panels. the shell is in pretty good condition, alot better than most I've seen, but for some reason the panels are all fucked. So we set about stripping off all the doors, bootlid, bumpers and bonnet so i'm just left with the good bits. Getting replacement panels already in white delivered on sunday so i can start putting it all back together again and it'll look a million times better.
I was going to take some pics last night but clean forgot until i rolled it back into the garage, promise i'll get some next time though!
