Make sure you relieve fuel pressure. Unplug the IFS switch in the trunk on the driver's side behind the carpet. Start car...let run until it dies.

Fuel filter is under the car. In front of the tank. Disconnect both ends of the filter. Replace filter. Connect fuel lines.

Oh...and don't **** up the clamps on the filter.

A mouse made a nice lil home in there. After taking the junk out, cleaning the maf and tb, and replacing the air filter, it runs like a champ.

May or may not be your problem, but since it sat for 4 months, it might be worth checkin out.
As I was reading this thread I was thinking, I need to post that mouse nest in the air box pic... and there it is! lol
