Sounds like a bad fuel pump. If you turn the key on and don't hear it run, it is the most likely cause. You may be able to smack the tank and get it working again, but will need to be replaced. If not, look for power and ground at the pump connector when key is on.

pull line off of front of filter and cycle key 2 on position if there is no fuel present your feul pump may b the problem, before replacing old one make sure the fuse is good

The fuel pump should be in the 20s. Also it could be losing presure slowly. Leave the fuel pump pressure gage on for at least 2 to 3 hours to see if it is losing pressure - It's a start
SOURCE: wont start, sprayed quick start in still nothing,
You need to check for spark. You probably do not have spark causing the engine to flood. Check your ignition parts and see what shape they are in. If you have not had a tune up in 50,000 miles you may want to start there.
