check wiring by coil,plus try and bypass small black signal filter near coil ,has red and green wires on it ending in small sealed filter unit-PJ

I have the same problem, a auto sparky has been telling me that on the cossy the signal is straight from the ECU to the counter plus an ignition negative.. Is this correct? I guess if the ECU wasn’t getting rev signal from wherever it would be running like a dog?
