The first thing to do is refer to the pin = assignments in the manual and check wiring on the pins on the plugs.  Start with = pin 9 on plug 3; that’s the 12v supply. Then grounds.  IIRC; the = display gets powered from the connection to the AQM, so check pin 1, plug-4 (grnd) = and check for 5v on pin2 to the display or pin 8 out of the AQM box.  Then go = from there.

 

Best of luck,

The engine started after only a couple of minutes the first time and = then

Thanks again.
