Narrative:

We were coming off the WAHUU2 STAR into den. ATC gave us a head off 200 to intercept the course for runway 16L. This heading was going to put us in front of the FAF when we intercepted. Once we saw that the intercept angle wasn't going to work then ATC directed us direct to the FAF. The FMS was not set up correctly and the mode the aircraft was in did not allow it to intercept the course. The glare of the sun made it hard to visual see the mode the aircraft was in and hard to program the FMS. By the time we realized the aircraft was not capturing the course we turned the autopilot off and hand flew. We turned back towards the course for 16L but already went passed it and headed towards 16R. We remained in visual separation from all aircraft the entire of the incident. Once back on course we proceeded with a go-around maneuver. ATC then gave us vectors for 35L and complied with all instructions and landed onto 35L safely with no other issues.poor coordination with ATC and the poor use of automation with the FMS. The environment of the sun glare making it difficult to see the instruments. Monitoring the modes of the aircraft and better use of the FMS to where it is set up properly and having better use of CRM.

Title: CRJ-200 flight crew reported executing a go-around due to unstable approach resulting from poor ATC vector and flight crew automation mismanagement.

Narrative: We were coming off the WAHUU2 STAR into DEN. ATC gave us a head off 200 to intercept the course for RWY 16L. This heading was going to put us in front of the FAF when we intercepted.

The FMS was not set up correctly and the mode the aircraft was in did not allow it to intercept the course.
