I have been running a hei with a tuned port injection system for over 15 years. I never use any module except for delco. Believe me I have been through many of them. I continue to have a problem staring my Blazer occasionally. This happens once every three more or every six months over sometimes more often. I found that I have good fuel pressure but it won’t Fire. So just keep a can of staring fluid give a two second blast in the air filter and it start right up. I have replaced parts cleaned injectors and I have found the starting fluid solves my problems and I stopped replaceing parts
