Narrative:

Was given clearance to proceed directly to facia and intercept the localizer for runway 31R. About a mile from facia I began to get a TCAS TA. While looking for traffic I missed the intercept and flew through the localizer perhaps 1/10 of a mile or less. ATC issued a turn back to the localizer. I continued to get the TA during final and while taxiing into the FBO.ATC did not say there was any conflict or problem from the deviation.maintenance has been alerted.corrective action: I had the number two VOR set up for the ILS. I should have had the number one set up as well or had the approach set up on the FMS so when the TA occurred and I was distracted looking for what could have been a false echo; the aircraft would have made the turn inbound on the localizer. The approach should have been flown as if in IMC conditions; even though we were VMC.
