Hey all. Having some issues with my distributor. I recently converted to EFI and MS3. Things were idling well, and then after I tried to make some timing adjustments mechanically my distributor stopped sending an RPM signal (via the green wire) to the ECU
After troubleshooting I can get it to send a signal, but only at the far extreme end of the timing adjustment swing, like the last few mm’s (see photo). Just a small movement back from this location, the sending of RPM signal stops. The green wire is intact and not the problem, and adjusting the wires position or bend etc does not change, even intermittently, the successful sending of signal or lacktherof.
Is there any reason the distributor would only send a signal at the far end of the timing adjustment and nowhere else? Bad internal sensor etc.
Thanks, really confused on this one.
