Let's get back to basics. Have you CHECKED all of the fuses in the engine bay and driver's kick panel?
Is the battery fully charged and are the terminals clean, corrosion free, and tight? Do not cut corners with regards to the battery and charging system. Today's cars will not run right without a strong battery, good cables, and clean grounds.
It's not recommended to test the spark by grounding with a screw driver. Today's ultra high voltage ignition systems can be damaged by arcing.
Turn the key on but do not crank. Do you HEAR the fuel pump prime for 3 seconds? If not, STOP and find out why. The car will never start if the fuel pump does not prime.
If the fuel pump does not prime, test for +12 volts at the trunk IFS switch. If no voltage, the problem is with a blown fuse, CCRM, or wiring.
If voltage is present, the problem is a bad fuel pump, bad FPDM, or bad PCM.
Post the results of the tests and will go from there. Again, it is vital that all fuses are good and the battery is good.
