Is there voltage at the fuel injectors with the key on?
You are correct in assuming that having spark should also
allow an injector signal and thats where the problem is.
If it runs when there is fuel present, then go to the
injector connector and back probe the red wire and see
if there is voltage(should be battery voltage 12.8V)
this comes through the main relay. The DME then
controls the injector pulse width by bringing the brown
wires down to ground for the amount of time the fuel is to be injected. The small green box is the idle control module. Look in the area above the DME and see if there is a black wire that is disconnected. It brings the DME the
signal from the coil.
