I've looked them up and not too much about them here. Just wondering if anyone has any experiences and could you share them if you do. Thanks in advance.

 

RPM signal - Ne or G signal to ECU
Ignitor.

You usually get these signals if it takes a long time for your engine to turn over, or if your ignitor is going T/up, or a bad ground from the coil/ignitor to the ecu.

Take Care!
