Honeywell Q345U1005
Disconnecting and reconnecting some electrical connections 2 - 3 at a time seem to help the system recognize the pilot is ready to light the furnace. The pilot cycle needs to cycle 1 - 3 times before the furnace functions normally (lights). I suspect the electrical conductivity in the ignitor is wearing out do to the heating and piloting cycles.

Answer: 
Grainger has contacted the product supplier and has been advised by them of the following.

The 36Z439 spark pilot assembly uses the spark rod to light the pilot and as a flame sensor. When the rod is energized it will create a spark between the rod and ground hood to light the pilot. Once the pilot is lit the rod sends a millivolt signal back to the spark module allowing the gas valve to open and light the main burners. If the pilot is not lighting on the first try, there could be several issues including a bad spark rod or spark module. If you have more questions you can call our HVAC tech support team at 800-472-4643.
