Okay so here's my dilema, my C3 decided to stall at a stop sign yesterday and it wouldn't start. By the time I was able to get someone there to pull me to my house it started up again but stalled after 20 seconds or so. We towed it to my house and after talking to a few local shop guys they thought it sounded like the fuel pump is bad. I put a pressure gauge on it and its reading around 48-50. I drove around the block a few times with the gauge on and it stayed the same for the most part. The only code that was thrown was bank 2 #1 o2 sensor malfunction which has been thrown for months now.

While testing the fuel pressure, the truck would stall randomly. I got it running again I got it into the garage and that's where she sits right now. Does anyone know of any tricks I can do to try to find what could be wrong with it? I just started the truck right up no problem now. I took the bed off tonight since I just filled the truck up yesterday too and I have a delphi fuel pump and regulator along with a new filter coming tomorrow just in case, I figured if nothing else the fuel pump assembly should fix the broken fuel gauge.
