My T-Boss 410 died hard on a run up the driveway and wouldn't restart. Cranks over fine, 12v at coil, fuel in cylinder (from plug check), and wire from computer to coil buzzes out OK. Computer threw a P0351 ignition coil malfunction message. I pulled the coil, measured resistance across the primary, and it was about 0.8 or 0.9 ohms, nominal for most ignition coils. I measured the secondary resistance as well and got about 6.5K ohms, also nominal for most coils. I checked the plug wire resistance and it was about 5000 ohms, which seems OK. And really perplexing, my spark tester shows spark. I got to feel it too, when I held my fingers too close to the conductor. 💩! Have any of you folks run across this?
