Any smoke when cranking?
Also feel free to more than "tap" that starter my truck sometimes wont start I can hear the starter click but no action. Usually a good hard thud gets it moving if not like the last guy said try having someone bump the key repeatedly at safe intervals while you hit the starter.
Sorry its late its not cranking heir go no smoke
I have also heard of pouring water on the injection pump as it can over heat as well I think. But im also a shaeyard mechanic dependent on these kind of sites so try at your own risk.
