Edit: Its a 3.4L engine and auto.

Ignition and fuel would be the best starting point. Although fuel is coming out the Schrader valve when pressed it doesn't mean the fuel pressure is correct. Possibility of fuel pump, fuel pressure regulator or fuel filter. So the fuel pressure should be checked with an automotive fuel pressure gauge.
Also pull one spark plug and check for spark.
