OK this is weird. The other two cylinders show power from red 12v pin to center ground pin. They both show power from red 12v pin to the one on the opposite end with the key in the accessory position but the difference is that when you crank the engine the power does not drop like I saw in the cylinder 4 plug.
Not sure where to go from here.

The wiring diagram shows 3 splices to the ground wire. Use ohm meter and put one end on the the center wire the other end on a good ground do all of these have a good ground. State readings and reply. Do the same thing to the other wire not hot. This goes through a condenser and also an ignition failure sensor to ground is the reading the same on all 3 wires.
Use a 12 volt test light one end on a good ground does the red wire blink when cranking on any of the hot wires.
I think a splice connection is loose but am not sure.
