Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, proposed preliminary tries (if have not been done):

  • • presence of IGN+12V on the black/white wires of the ignition coils;
  • • presence of ENG+12V on the black wire of the ignition control module;
  • • 0V at the light green/red wire of the ignition control module;
  • • good ground connection of the green wire of the ignition control module;
  • • pulsating low voltage between the blue and white/blue wires of the ignition pulser to the ignition control module when attempting to start;
  • and pulsating voltages on the yellow/blue and blue/yellow wires of the ignition control module to the ignition coils also when attempting to start.
