Sounds like the Fuel system control module is shorted out. Have you tried rebooting the system by disconnecting the battery cables for 5 minutes letting the modules discharge and try again?
Yes I am afraid the module is in need of replacement and it does need to be programmed with a tech2 or equal scan tool to program.
With the short the signals sent from the fscm to the computer will not allow spark.
Once you get it replaced everything will go back to normal operation.
