  1. Oh no tuner. May have been one previously. It has some kind of old BD monitoring system. The fuel pressure sending unit has 3 wires. One actually is tapped into the map sensor. Don’t understand that one. Need to look again to make sure I’m not crazy
  2. PCM P1693 ECM 0234, 1698, 0341, and 1690. Replaced CPS, new Air Dog Lift pump, new injectors, new penciles. Some times it has full power then randomly loses power won’t boost over 15-17 psi
