I did the Igniter Unit Input test.
#3 BLK/YEL had battery voltage.
#4 WHT/BLU had battery voltage.
I also check the coil. The primary winding resistance was 1.3 ohms (just outside of the specs of 0.6 to 0.8 ohms, however the temperature of the coil was a little higher then the specs of 68 degrees (it was about 75 to 85 degrees). The secondary winding resistance was 16,940 ohms (which is within the specs of 13,200 to 19,800).
Would this difference in the primary winding resistance be enough to cause a no spark situation? And can a faulty Igniter Unit cause the coil to go bad?
I checked the wire WHT/BLU between the coil and the Igniter Unit and had battery voltage.
#5 YEL/GRN which changed colors, after a connector, to PINK, then went to the computer. Had continuity from YEL/GRN wire that goes into igniter to computer on the passenger side just right of foot area.
I think that was what was meant by PGM-FI ECU, but not sure.
#6 the BLU wire which also changed colors to RED/GRN also ran into the computer, also had continuity from BLU wire that goes into igniter to computer. How would I then trace it to the tachometer? Up to the tachometer gauge?
Thanks again for your help.
