Answer
Hi Jason,
I would check the fuel injector fuse, and check at the injectors to make sure they have power.
Then make sure the ecm is pulsing the power. You may want to pick up some "Noid" lights to check for injector power and pulses.
Is the pressure around 14PSI?

Try holding the gas pedal about half way to the floor. Not all the way.
