Starting problem

Maybe its your main relay, the solder joints might be going bad or something.

^this is quite common. Try hitting/kicking the main relay and see if it starts.

Sorry guys, I've been busy with work, haven't had much time to look at it. It's been running lately so I've left it alone, but I'll check everything that you guys have suggested hopefully by the end of this week and I'll get back to you.
Thanks!
