Hello and welcome to just answer Dodge. Yes you will need to bleed the system in order for it to start. Do this: loosen about 3 or 4 of the fuel injector fittings on the head. Loosen them about 3/4 of a turn. Then crank the engine for about 20 seconds, pause for about 30 seconds, and then crank again for 20 seconds. Repeat this until it tries to start. if it does start, then turn it off and re tightened the fittings and then restart the engine. It will run rough for a few seconds, but will eventually smooth out.
Hope this information helps, and let me know if you need more assistance with this.
Yes keep trying. Sometimes it takes a while. leave the fittings loose until it acts like it is trying to start. Then tighten the fittings,
