Hi James Curley,
Thank you for the donation.
The fuel pump should prime for 2 seconds until the Check engine lights goes off during initial ignition on condition and will continue to run when engine is running. When engine stops/stalls, the fuel pump should stop working.
For the year model, the PGM-FI maiin relay is known to fail intermittently causing the fuel pump to stop. Remove the relay and check the circuit board for cold solders. You can see cracks on the solders and resoldering would make the relay good if not better than new.
When this relay fails, it is intermittent so bench testing might not get the correct results. You are correct about the system working so I believe you have got the system and wiring correct.
With direct power from the ignition to the fuel pump and having to tow back indicates either the circuit has a fault or the fuel pump is bad and fails intermittently. Check the fuel pump grounding, it could be poor causing the fuel pump to fail intermittently.
