Not getting a RPM signal. Just keeps reading "STALL" even when its cranking. Stock ignition system. Ignition coil to distributor. No external ballast. Yes, yellow wire from SNIPER is going to negative side of the coil. 1 yellow wire only from Sniper kit.I suspect you're not getting an RPM signal to the Sniper from the coil. Its sputtering from the prime shot but without an RPM signal it will never continue to inject fuel. Stock ignition system? Correct yellow wire to the negative side of the coil? (I think there are 2 yellows)
I'd ask over at Holley Forums if the wiring checks out OK
just to clarify. It NEVER shows RPM?
