Jez Ray, bless you for draining the tank! Go buy a fuel filter and use that to get the wrench size for the nuts on it and the lines...I don't remember if they are the same, sorry. Swap the filter, and do a pressure test alla the book flow chart or see Jeff's answer to Nate(sick 90) for a simpler way.
Gotta start eliminating places to look. If the fuel sys check out then ing sys is next on line. I would still say that if the fuel sys checks out okay I would borrow a scan tool and "look" at what the motor is doing. You can take out all the plugs and turn the key to "on" and smell all the plug holes...if the injectors are leaking you might smell the fuel or just turn the key on for a short time and then pull the plugs to see if gas is present. Obviously it shouldn't be and the injectors are leaking.
