well, i have two topics about the same filter going, but each wtih different ideas. As i said, i exchanged the fuel filter for the same part at autozone, but it is still doing the same thing. I also checked the fuel pressure realease valves ( i only found the one behind the water pump cam pulley), but they were nice and tight. The spark plugs are not an isssue, as the car fired up immediately 5 minutes before i changed the filter. I cannot smell any gas, and there were no visible leaks comming from anywhere under the car after 5 minutes of idle, and reving. As i said....it might just be the poor quality of the filter...the fuel lines don't even slide on all the way. There is about half an inch on the side where the fuel exits the filter

(but its not spraying fuel!) ...damn autozone doesn't carry purolator and the nearest pep boys is 15 miles away and i'll be out of $10 if it doesn't fix it

. The car runs fine once i get it started, but if i let it set for 2 hours or more, it takes 3-4 seconds to get it to fire up. if i get it started, and then turn it off, and then turn it on seconds after, it will come on immediately, indicating that it has to be fuel pressure leak - not a consistant spark plug, valve, or sensor problem.
