    hello everyone I have a 1994 vfr 750 that has no spark, I checked everything with a multimeter which included the coils, the battery, the stator, all the wires that go into the ecm, and everything in between and it all cam back good but still no spark. I had it running awhile back perfectly fine so if anyone would kindly help id greatly apricate it and if you need any more details just let me know ill post everything I can.

    Hate to be that guy but have you checked your HT leads condition? And the spark plug caps themselves?

    will do since I had it running 2 years ago but since I was a over the road truck driver it just sat and now it has no spark and I figure its not my coil packs since they wouldn't all go bad at the same time so ill keep you updated once I figure out whats wrong

    Out of curiosity have you changed for new sparks? Or checked the gapping?

    Does your tach bounce when you crank the bike? If not then maybe the ECM or the crank sensors. A DMM should show the pulses from the crank sensors as a small AC voltage if your meter does not have a frequency measurement function.
    (Meters with this function are cheap these days)

    Also note: this is the 5th gen VFR800 forum.
