You say you have a T5, do you have a clutch safety switch not hooked up? Get someone to put in neutral, push the clutch in and try to start. Then you take a test light to see if the small wire on the sol. goes hot. If not, it's the clutch switch, wiring or ign. switch. If it does light the test light, you have a bad starter, wiring problem or starter/engine isn't grounded.
