Answer
Hi Gene,
At that nipple, a pressure test would be nice. But any pressure is better than none.
Depending on type of injection system, you probably need 14 PSI, but multi point injection system needs much more.
Check to see if you have power to the injectors. One side should be hot with the key in run.
Noid lights will tell if they are being pulsed.
A little shot of starting fluid or gas in the intake may tell if spark is good.
