90dsmturbo Posted November 25, 2015 Report 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
Scott Posted November 25, 2015 Report 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
