The only thing I can think of is the coils are not pulled out far enough. You said the turbine ran, then it would not start, then you checked the glow plug and it was open; then you replaced the plug and the haven't got a start since. Only thing I can think of is the coils are not pulled out far enough, you need 2 coils pulled out of the plug. use a needle or a pair of fine tweezers.
