He might need more help, as to what you want him to put the NOID light on.

If you have spark, and can start with priming the TB with fuel or starter fluid as you said, I would look somewhere besides the distributor.

Pinout should be the same between 6395 and 7427.

If you have the dog house in an RV that you can watch the TBI from the driver's seat, I would test to see if you get the key on prime pulse. When keyed on injectors should fire a priming pulse. You should be able to hear them if you listen, and should be able to see fuel squirt.
If I remember correctly, the fuel pump relay is only used during cranking, and PCM takes over after that. You could jumper the relay to verify you hear the fuel pump running, might require a helper with a 30+ft RV

Without being hands on, that's the best I'm able to offer hope it helps. I would suspect a connection somewhere.

Sometimes trouble shooting is the hardest part.
