Message	I have a 1992 TT 300zx. Number 1 cylinder not getting spark. Took the CAS out and spin it to test for spark, no spark. Coil pack is good cause I test it by hooking it up to another cylinder. I have a new 2nd generation PTU. Engine wire harness is brand new just installed. Check the Ohm and get no reading. Could the PTU cause one cylinder to not spark?
