If I remember right, the regulator has a small hole in it to bleed off air and a spring loaded valve to control fuel pressure.
As far as cracking lines to release air, there are no injection lines to crack on a heui engine.
Mechanically, all you have to do is provide fuel to the lift pump, and oil pressure to the injection pump, and it should light off. If it doesn't, then you check the computer.
The regulator was damaged, it was not maintaining the correct pressure.
