Man, this has been killing me for a month. Long story, try to make it short. Put Holley sniper on last winter. Was running great for 6 weeks, then became inconsistent, would run great then die. Start it would sound like it’s on 5 Cylinders. Next day run great. Holley thought rfi so I rerouted wires. Had a thread a couple weeks ago about how I had it hooked up to ign 1 & 2. So tried starting it today and it won’t run. Power to the handheld is good, which shows 12v from ign 2 when cranking, ign 1 when in run. But Sniper is not showing rpm so it shuts down immediately after the prime shot is burned. So is coil not getting enough voltage in run to keep it going? It may be the efi, I’m trying to eliminate ignition from being the issue
Ballast resistor ohm checked at 0.8, which is what the msd coil calls for.
