90dsmturbo Posted November 25, 2015 Report Share Posted November 25, 2015 Hey guys I am having an issue with a g4+ atom I am installing. Its a TFI setup using a TFI module for the rpm signal to the link and a 50% duty cycle output for ignition. I get rpm, I have spark but it doesn't seem like i a getting any injector output. I tested the injectors using the injector test mode and the car starts and runs off starting fluid perfectly fine. I am going to get some help to put an LED into the injector plugs and check if i am getting any cranking pulse but besides that any reasons why I may not be getting fuel while cranking. My current ideas are check for 12v while cranking besides that I am out of ideas. Quote Link to comment Share on other sites More sharing options...
Scott Posted November 25, 2015 Report Share Posted November 25, 2015 I think we may have talked earlier about this already. The other thought that comes to mind for me is to make sure there is good fuel pressure. Quote Link to comment Share on other sites More sharing options...
