there is a schrader valve on the fuel rail by the valve cover as alloro said. Turn the key on , the fuel pump should run, then shut off after 3 seconds.......... go to the Schrader valve and poke the center pin ( not at your face) and see if you get a short squirt of gas out of the valve. Should have 30 psi or better if pump is working and fuel in the lines.

 

Have you checked to be sure the air filter housing is not full of rodent nest?

Also make sure it is getting spark.
