No, purchasing a seat in United Economy Plus does not automatically grant you priority boarding. United Airlines treats Economy Plus primarily as an "extra legroom" product rather than a separate class of service. Passengers in Economy Plus typically board in Group 3, which is the same group as those in standard United Economy seats. This is a notable difference from competitors like Delta (Comfort+) or American (Main Cabin Extra), which often bundle early boarding with their extra-legroom seats. To get priority boarding on United (Groups 1 or 2), you generally need to have MileagePlus Premier elite status, hold a qualifying United credit card (like the Explorer or Quest), or purchase a separate "Priority Boarding" add-on, which can be added to an Economy Plus ticket for an extra fee. The only exception is if your Economy Plus seat is located in an exit row, though you will still board with your assigned group unless you have one of the aforementioned status or credit card perks.
