My Dart Swinger Project!

Electrical demons are maddening.30 years ago on my 350 efi landCruiser I had 6a Msd, i installed a 4 injector throttle body Injection kit too. My buddy who's an expert in this field, owns and operates Imagine Injection could not get fire to ignition. He ultimately pulled the MSD and tried GM HEI, worked perfectly and still in the truck today. Maybe this helps, idk. Good luck
