Will not start after a 13-year hibernation, 1973 2.0 D-Jet Options

[Alden]

Ran well before storing in a dry shed.

Evaluated the fuel system and installed new:
fuel tank
fuel level sending unit
fuel tank screen
fuel filter
Cohline 2240 & Gates Barricade fuel hose
rebuilt Bosch 3 port fuel pump
(4) Standard Motor Products JF67 Injectors

Verified the stainless-steel tunnel and engine fuel lines are clear.

Applied 12 volts directly to the fuel pump to prime system. Fuel is circulating (can hear the gurgling of the return in the tank).

Ignition in the ON position the fuel pump primes (can hear running for 1-2 seconds).
Ignition in the START position fuel pump runs (verified with voltmeter, can't hear running due to engine cranking).

Ignition in the ON position apply throttle can hear fuel injectors click.

Engine will run with starting fluid.

Could it be fuel pressure? Fuel pressure regulator go bad from non-use or E10 fuel?
(E10 fuel destroyed my Cohline 2134 fuel hose and Bosch fuel pump)

Don't know if this could be a factor, sometimes in the START position, nothing, have to return to ON position and retry. Failing ignition switch?

What else should I look for?

When the key is turned to the accessory "ON" position (no engine cranking) the fuel pump comes on for 1-2 seconds. I apply the throttle and hear the fuel injectors click. I then unplug the fuel injection harness connectors from the injectors and plug in the noid light and apply the throttle and the niod light lights up.

When the key is turned to the "START" position (engine cranking), fuel pressure rises to 26 psi, engine doesn't attempt to start, just spins. I then unplug the fuel injection harness connectors from the injectors and plug in the noid light, key is turned to the "START" position (engine cranking) and noid light does not light up.

The above is incongruent with "engine will run with starting fluid." Not sure what is going on here, could be something simple like a bad connection somewhere.
