Problems with mine were. I would put key in turn it and nothing, Lights would come on on the dash but not a sound but a clicking sounds fom the engine. Not even an attempt at turning over. Just dead. Then a trusty whack to the starter motor with the hammer and it starts.
i had a similar prob with mine and it turned out to be a bad earth!
one of my mates suggested running a cable straight from the starte to the battery. when i began the work on it, it turned out one of bolts which holds the starter to the engine was well loose and a film of oil had got between the mating faces.
so i cleaned it and tightened the bolts and its been sound ever since, no need for direct earth cable either
