My 2003 chevy Cavalier has been experiencing intermittent startup issues and occasional "chugging" while driving - seemed like the car would lurch ahead at times, has also briefly stalled at lights. On 10/11/08, the car would briefly turn over and start for less than a minute, shut off, and afterwards refused to start. Had car towed from my residence to mechanic shop who alerted me that fuel pressure was low. Fuel electronics were functioning as per computer check, turned out to be a bad fuel pump. Car is at ~110,300 miles. Had spark plugs, fuel filter, engine belt replaced in March & April of 2008.
