well i thought I would finally respond to this post. I Checked the fuel pressure and it was 10 lbs below specs and no vacuum leaks so I went with a new fuel Pump Module..This car does not have a fuel regulator. It is a returnless system with no return lines to the tank. The pressure is maintained by the fuel pump Module. if the Pump is weak then so is the FP.. I found a Ford / Motorcraft fuel pump on Amazon.com for $139.00. could not believe they were almost $175.00 less than the local dealer. It was a quick repair and I have had no problems or CEL since. The day after I ordered my pump Amazon had raised the fuel pump to $189.00. Supply and demand for you. So if you are in need of parsts, dont forget to check Amazon. They have some good deals..
