A couple weeks ago I had 2 coil packs go bad, fixed problem-easy fix, car ran great. Last sat night car ran great for hot laps and heat started right up with starter no problems, went to go out for main event car cranked over fine with starter but would not light, I pushed him off with ATV it fired right up he ran main car ran great, had to be pushed off again during main after a red flag, again car fired up ran fine. Now is when things get ugly, after main went to fire up car again and nothing, wont even start with being pushed by ATV. Ive got plenty of fuel pressure its getting fuel cause it was blowing out pipe at me while pushing, just not lighting. I pushed it in trailer that night, started checking things out today and there is no spark at all on any of the coils. I replaced battery (getting a little sluggish) replaced all terminal ends for all my ground wires, I checked ohms on crank position sensor (within parameters that Yamaha calls for) I swapped out another cam position sensor I had off another motor ive got, Checked ohm reading on stator (good)still have got no spark! Im at a loss here folks! When I turn on ignition switch I here the normal clicking that the injection makes so I know that is all working fine, batteries got plenty of voltage (its new, it should) one other thing that was a little strange after main is I got a really weird reading on my tach saying that it only ran 1800 rpm, not sure if that's related to anything but thought id throw that out there. Any help would be greatly appreciated! Thanks Dave
