Check for fuses/power/ground to the engine computer (or injector drive computer) whatever the case is.
Spark, fuel pump, and starter all are independant of the fuel injection computer.
Either the computer itself has gone bad, or it is not receiving power or ground, or wiring to the injectors might be bad...

Check the wire from the module to the crank sensor. They go bad. Usually from oil leaks. Is it saturated with oil where it goes under the engine? Also check for power and ground on the two wire plug on the drivers side of the module. It isn't the ecm or anything with it. The ignition system on the 3.1 will work with the ecm unplugged. The ignition system is a stand alone system. It sends signals to the ecm for the fuel injection.
