2006 Forenza Fuel Pump problem?
 

I have an '06 Forenza with 133K on it. I'm having a hard time getting gas to it (seems to bog down). It hasn't stalled on me yet, but sometimes wants to. Check engine light flashes on and off at times and stays on at other times. I called Suzuki and they said almost $600 for a fuel pump, but it could be the PCM? Any ideas? Thanks.
