Step 4 (Start the engine and clear all air from injectors)
Reduce the throttle from full open to a high idle before cranking.
Crank the starter.
The cylinders should start to fire. When they do, you will hear the engine try to speed up, hiccup, and almost start. If it doesn’t start after 15 seconds, wait the 5 minutes.
The next cranking session usually causes the engine to start up and run. If it doesn’t, there may still be air in the injector pump or some other issue. See "Troubleshooting" at adamrbecker.com...
When the engine starts, adjust the throttle to a high idle if it isn’t already.
The next step involves cracking the injectors, so a high idle is required to keep the engine running.
The engine may be running, but is it running on all cylinders? The next steps will ensure all injectors are air-free.
Crack the first injector.
The engine will stumble but hopefully keep running.
Stumbling is good. It means that injector was running well before you cracked it.
Another good sign is fuel pulsing out in high-pressure squirts.
If no fuel is squirting out, wait until it does.
Tighten the first injector when clean fuel exits the union and the engine should run smoother.
Continue for the rest of the injectors.
If all injectors are bubble-free, each of them will cause the engine to stumble when cracked.
