Scott Posted June 15, 2016 Report Share Posted June 15, 2016 On the S15 plug-in ECU Ign 2, 3, and 4 do go through the jumper pins, so there is a good chance the jumpers may need to be adjusted. If engine speed is reading correctly in PCLink then that means you have the 4 mini switches correct. Try setting the jumpers in whatever position they are not currently in, as per this image.Scott Quote Link to comment Share on other sites More sharing options...

Smokedogwest Posted June 18, 2016 Author Report Share Posted June 18, 2016 (edited) Tried swapping all jumpers around ended up with no tacho and no 3/4 coil packs. Swapped them back now have all coils ,injectors and tacho now but still running on two.could it be fuel?brand new 1000cc injectors Edited June 18, 2016 by Smokedogwest Miss spelling Quote Link to comment Share on other sites More sharing options...
Scott Posted June 20, 2016 Report Share Posted June 20, 2016 Try using the Ignition Test function (ECU Settings > Ignition > Ignition Setup > Ignition Test) to verify if you have spark to each plug. Likewise you can use ECU Settings > Fuel Fuel Setup > Injector Test to verify that each injector is activating.Scott Quote Link to comment Share on other sites More sharing options...
