Symptoms seem odd. Outline of the sequence of steps...

1. Crank, no start. Have spark and compression.

2. Disconnect fuel line to dampner. Small amount of gasoline spills out.

3. Car starts with damper line disconnected. No fluid coming from disconnected line (had container attached to collect).

4. Reconnect dampner line. Crank, no start.

I initially disconnected the dampner line to check for fuel pressure but the retaining spring on fuel pressure guage broke when connecting.

Car isn't driven much but gasoline is only 3 months old and car is started weekly.

Thoughts?

Fuel pump was going out intermittently. With new pump, started immediately and engine ran perfectly.

Just a heads up: Those checklists were written for fuel injected Windsors. Some of it may or may not apply.

Good job finding the fuel pump.
