Spark Problem! Help PLEASE! I have posted another thread on this topic no answers.

Sparking from only ONE coil.
Does ANYONE Know the voltage readings for the ignition coils. I have only ONE fire on the #1 Cylinder.
Voltages to all Pink wires are 12V
Voltage to Purple #1 Ignition Coil when Cranking goes to 1.5~ ish Volts.
Any other color / Ignition coil the colored wires do not show anything but mV
but they do jump when I try to start the ignition.
All pink wires on coils hold power while cranking???
I have no clue where to go from here.
I am buying another PCM hopefully tomorrow to see if this checks out.
Only DTC's set on my reader are EGR and EVAP system.
TPS seems to be working on my reader also I am seeing RPM when cranking.
So I am ruling out the CPK Sensor.
I just need someone who can help.
I am also wondering if possibly someone can check / has info of voltages of the ignition coil wires (Non Pink) Voltages while cranking.

The "non pink" wires are the ground side for each of the coils.
The pink is a common 12+ feed to all the coils. The pink has to be hot, when key is on, and when cranking.
Check the plugs on the coil harness.

SUCCESS ..... It was not the harness or wiring. Also by "non Pink " I meant not black ground wire or brown common ground to pcm.. I meant Ignition control wires sorry for confusion. I just purchased another junkyard non 411 PCM 30 minutes ago... Fires right up first try .. apparently I bought a bad PCM off of ebay.
