Do you have spark & fuel pressure? If so, you may have a bad PCM, or any or all of the following:
DTC P0107 Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage
DTC P0108 Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage
DTC P0121 TP Sensor Circuit Insufficient Activity
DTC P0401 Exhaust Gas Recirculation (EGR) Flow Insufficient

Yes there is spark.
Fuel not sure. Is there an easy way to check it?

You can check the fuel pressure @ the fuel rail schrader valve, using a fuel pressure gage. Most of the popular auto part suppliers have the gage in stock.

FYI the car will fire for a split second with a battery disconnect/reconnect.
