The car has a walbro pump. I ran it on my redtop with the stock FPR without any problems.

OK... I tried some more stuff without luck...
-CAS
-Ignitor
-Ignition harness
-Took off the tach signal thinking maybe I wired it to the cylinder #2 ignition signal

I am down to an ECU now. Could the ecu send a very weak signal to the coil and cause it to barely spark? The whole problem is that the 2nd cly's coil isn't firing. After removing the tach wiring, I fired it up and it ran fine for like 3 mins, then went back to not firing on that coil, so I don't think it could have been that wire. Maybe I bumped something near the ecu when I was messing with that tach wire and that's what caused the car to run good for a min, I dunno. I hate problems like this. I always seem to get stuck with weird problems, lol. My wiring harness is brand new from nissan also, so it shouldn't be that at all. Anybody want a 3cyl s13 for $10?
