My focus would not start, I replaced the fuel pump and filter and it started. I drove it about 10 miles. The next morning it stared I drove it a few miles and it quit, I started it again , went about 300 feet and quit and it kept doing this. I then replaced the fuel pump driver module located under the back seat, this still did not fix the problem, it starts fine and runs at a idol if I try to give it gas it wants to quit. what could be wrong with it now ?

  1. Have you checked your fuel pressure to see what it is at idle and to see if the pressure drops when you hit the gas?

    Could have a bad MAF- Mass Air Flow Sensor or loose hose connections at the MAF Sensor.

    Any check engine light codes?

  2. Sounds like MASS AIR FLOW SENSOR I HAVE SEEN THIS PROBLEM AND IT NOT GIVE A LIGHT OR CODE
