Haven't checked spark, but I shouldn't be getting any if the CPS is not reading. I have been checking the voltage directly from the CPS unplugged so wiring is not the cause of the low voltage, I have replaced the wiring harness plug with a new one though. Have a NTK sensor coming in today, if that doesn't work I will try the boring out trick that I missed on Cruiser's site. Fuel is fine, 35lbs.
