Default '94 ranger not sparking on two of the 8 wires

ARG! My '94 ranger won't spark on two of the 8 plug wires. I noticed this a while back, the front coil pack was not sparking on the right side. So I replaced the coil pack, AND IT STILL DOESN'T fire on the right side! help! what am i doing wrong?

Default Re: '94 ranger not sparking on two of the 8 wires

I just spent 2 days on the same problem. The secondary coil would not spark on 2&3 cylinder. I finally took the Ignition control unit off the the intake manifold, cleaned the mounting area , applied new white lithium grease, cleaned the 3 mounting bolts and re-installed the ICM . It has work good so far. Forums i read said the heat may effect the circuit and it has to have a good ground thru the bolts. I do not know how long this will last, may be going bad internally and have to get a new ICM but at over 100 dollars i want to put it off if possible. My truck was also showing a fault code 224. Hope this helps.
