1) First test whether the dizzy gets battery voltage.

2) To test the Yel/Grn wire for an open or short, disconnect the wire at the ICM and disconnect the ECU connector where the wire is routed to. Open test: Use a multimeter to test continuity of the wire between both ends. If there is no continuity, then the wire has an open (= broken wire). Short test: Use a multimeter to test continuity to ground at each end of the wire. If there is continuity to ground, then the wire has a short (it's grounding out due to damage).

Culprit was the coil... Tested good but swapped the thing with a blaster2 and it now runs smooth and only throwing a code for o2 sensor 1 low volts. Any way to correct this? Or do I just need to replace?
