1 = 3C GN/O
2 = 4c Y/GN
3 = 4D W/BK
4 = 3D BE/GY
Measure voltage to ground not wire to wire.
Pull the relay and turn the Ign on and run switch to run. BK/W and BE/GY should have 12V to ground.
Pull the fuse just left of #2, should be the fuel pump fuse, and see if it's blown. If not reinstall the fuse and relay then ground the black lead, touch the red lead to the little metallic spot on the top of the fuse next to the 5 in 15, crank the engine and see if you get 12V.

Checked voltage when cranking between AD and AC and getting 5.5V on both

'08 FLHT. Had a similar problem last summer. Disconnected the fuel line from the tank, then reconnected, no help. Disconnected it again, and cranked the engine over with the line off. Reconnected the line, and it fired right off. Did that several times, no idea why. Hasn't done it since. Replaced the fuel pump, filter and lines about 3 months earlier, and had zero starting problems. Acted like a vapor lock on my old carbed bikes in the summer.

Because I am a moron, one time when replacing a CPK I put it backtogher wrong and pins were not lined up.
I find it interesting no spark and no fuel. If you had spark, I would say put some gas in plug just to see what happens.
Did you have both plugs out when testing spark? There was talk if delphi need a plug in to see compression. I tested it, and now I can't remember if true.

Having 12V on the Y/GN proves the CKP is giving the ECM a signal or it would not ground the system relay.
