4. Improper electrical grounds: “EFI systems don’t work properly if the grounds don’t go back to the battery’s Negative post.” Sensors operate under minute voltage variations, so any voltage fluctuations, resistance, or drop can introduce erroneous readings. Remember, the circuit’s ground-side is part of the total circuit length, and hence, contributes to resistance and voltage drop. A standard chassis-ground won’t cut it.
.....at the end of the read was the top 4 EFI mistakes this was one.......here is the link to the article.......................

.....I hope this shines a light on something we are not seeing...Rod Im sorry for your family's lost at this time........God speed and good luck...... |
I really really think it is a ground issue. But that would be a design flaw on FiTechs part. Cause they sure as hell don't have a ground wire or anything of that nature for the system. They are using the carb studs as the grounds. But when I called and talked and BS with them it was o runs ground from the carb stud to the battery. WTF... Give me a ground already terminated in the harness and let me ground it to the block or frame.
