JOEL Posted June 15, 2021 Report Share Posted June 15, 2021 Hi Everyone, Apologies for another thread, I just cant wrap my head around why I cant get any spark. New ECU install on an RB25 Series 2, Checked wiring for coils - OK, getting 12v Checked coils - OK Checked plugs - OK Trig 1 Signal - YES Trig 2 Signal - YES And I am getting approx 150-300RPM when cranking. Connected ground to plug body and tried cranking, no sparks. Any ideas would be great!Thank you Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 15, 2021 Report Share Posted June 15, 2021 Do you have a spark when you use the ignition test function? Can you attach your tune and a log of it cranking. Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 15, 2021 Report Share Posted June 15, 2021 If you have no spark when doing the ign test then there is a wiring or power supply problem. Quote Link to comment Share on other sites More sharing options...
