Narrative:

I was on socal approach frequency and I was told I had traffic 11 o'clock and 7 miles. Socal approach stated that the traffic 'appeared' to be on the localizer for the runway. I called traffic in site and then I was told by approach 'contact tower; maybe they can move them off the localizer for you'. Upon contacting tower; I was informed that the traffic was not talking to the tower. I had a traffic advisory call out from my TCAS. I made a left turn due to not seeing any traffic on my TCAS or visually off to my left. I was switched back to socal approach and told that I should not have made this turn. I was vectored back on the localizer and landed with no incident. My closure rate to the aircraft in front of me was too fast for me to continue ahead. It appeared the aircraft was holding on the localizer without telling anyone he or she was. I was not told to maintain visual separation either. Socal approach should have taken me back out due to the traffic and not asked me to continue inbound. He also should have let the tower and other traffic know that this traffic was holding on the initial approach fix to the runway as well as this traffic was at initial approach altitude. In my opinion this was a complete breakdown in safety by the controller.
