[QUOTE=ssks] I hear the starter turn for a second or so but then it stops. [QUOTE]

Based on the aforementioned criteria you may want to explore having the starter ring gear coated with some lubricant, anti-seize works well. The fact that you hear, or have heard, the starter motor engage momentarily leads me to suspect a dry ring gear, a known issue. The citeria is slightly different (ie: motor engages and disengages a number of times before engine finally runs.)

If you do not hear the starter motor engage then I might suspect the ignition switch, perhaps there is a fault with the 50 circuit output ???

Just my thoughts.
