EK9 RX Not Sparking

[Kieran Bailey]

Thought I'd post on here to see if theres any old school users with some big brains?

My EK9 isn't sparking. Previously the rotor arm bolt came out and went through the ignition control module. Since then, I have replaced the control module, the coil, the rotor arm and the Dizzy cap. Also changed the coil fuse under the dash. I've sent signals to the main relay from a pinout diagram to hear it switching correctly but I'm still not getting any spark.
Fuel pump primes fine and I can smell the fuel, and the engine cranks fine.

Wondering if anyone had any thoughts that I could test?

I think it's better to replace the whole distributor.

Try a used dizzy to rule out

Have you checked the wiring? Bad earth?

Sounds like the sensor that triggers the spark isn’t working. You could prove this with an oscilloscope if you have use of one? I did this years ago and proved it was a dizzy before buying one.

If you pop the fuel rail off with the injectors out of the manifold you could crank it and see if they injectors are firing in sequence, which would show you the Ecu / dizzy knows the position of the engine. You’re then looking at what collapses the coil, which you can prove with a scope. In my old build thread I think there are some pictures of me doing that…

Crank position sensor?
