call to FI Specialties was no help they simply said to recheck everything the people in this forum said to check. Their unit is plug and play,. I am using their ECU, their harness and their TB Fi unit. Car went to an electrical specialist and he had it running right for a day but when it came back and was unloaded from trailer , it ran for a block, drove in garage and shut it off. Went to restart and back out again and refused to start. Changed plugs, was running lean when it would run, now running rich when it will run. Taking it back to electrical specialist as he had the most (but short) success. After verifying all electrical issues were fine the only thing he did was change distributor and fuel pump. I appreciate the suggestions but everything said so far has been done checked and rechecked. thinking about starting over with Edelbrock E street unit and asking for refund from FI Specialties as I believe the problem is a gremlin in their product.
