are you getting voltage at the injectors? if no voltage then the injectors wont work, you should check out your cam and crank position sensors, you getting good spark?

you should have your cam and crank sensors checked. they controll spark and injector pulse. sounds like you have no injector pulse so you should have those two checked.
check the fuse and the throttle position sensor also.

sorry but i dont think its the ignition module as it deals with spark. but you have that.

i dont know where the sensors are located on your car, even if i did i wouldnt know how to test them on your model. plus if you change them they have to go through a relearn cycle anyways.
