Hey everyone. Well, I just got my SR20 running, and It is missfiring on cyl 3. It is getting no spark on that cylinder. So, I tested resistance of that coil, and It tested good. I also tried switching coils, and cylinder #3 still had no spark, even with the known good coil. I checked voltage at at the wires going to the coil, and they checked good, the same as the others. I also checked my ignitor chip by using the test method shown in the shop manual for the S14 and it also checked ok. I am thinking maybe a disruption in the signal from the ECU???? Please help ASAP, I really need to get the car done this weekend. Thanks. -Derek

I am having a similar problem. Except I cant figure out if my cyl#3 problem is no fuel or no spark. Keep us posted im curious to see how this turns out.
