My ignition started with a slow burning fuse.
As a kid my favourite bands were an eclectic mix of Adam & The Ants, Queen, Duran Duran and The Specials.  I always mucked around playing air guitar and such, but it honestly never occured to me to try and get a guitar (money was tight in our house).  After several years I somehow acquired a nylon stringed acoustic (I think my mum bought it from someone she worked with) and started noodling around learning a few (a very few) chords.  At the time though I was really distracted with writing games on my Commodore 64, so it didn't get the attention it deserved.
A year or so later I discovered the Friday Rock Show one night, with the sadly missed Tommy Vance (TV on the Radio! :)) presenting.  I can clearly remember some of the bands he played that night.  Saxon, Budgie, Marillion, AC/DC being a few.  I was blown away by some of the guitar work.  Then a friend of mine leant me a mix tape that he'd done which included tracks by Warlock, Dio, Magnum (and some others I can't remember).
That was it really.  I bought an Ibanez (some kind of SC strat copy, no idea what model) from said friend who had inherited it from a flat his parents rented out (the band living there had done a runner without paying the rent and left some stuff behind :lol:).  £50 I think it cost me.  Then mum came to the rescue once more and managed to get a small Carlsbro practice amp from someone she worked with (£80ish).  This thing was so cr@p that if you cranked the gain all the way up (the only way to get it even slightly distorted) it used to pick up police radio.  :lol:
Then I started listening to Iron Maiden, Kiss, Metallica, Yngwie Malmsteen, Marillion.
The rest is pre-history...
