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?

Those are good signs. The injector grounds seem to be functioning and so are the trigger points, all 4 injectors are clicking. You have fuel pressure as I recall, have you fired the injectors into jars or cans to verify fuel flow?

If it starts with starting fluid you should have spark at each plug.

Fuel, spark, compression.

Pull a vacuum on the MPS to verify it holds vacuum? It will be too rich to even start if it does not hold vacuum. Is your CHT sensor connected?
