eclicking sound when ignition turned on....but will crank,not start?

I have a 97 240sx with the ka still in it. When I attempt to start the car it will crank but not start. There is a loud clicking coming from the passenger shock tower. This sensor has some wires and a vacaum line ran to it also if you unhook the electrical connection to it you can then hear a more faint clicking from underneath the intake runners. Have any Ideas?

Check and make sure your fuel, spark and air delivery are in order. Sounds like you could have a problem with the car getting spark.

Its not getting spark and also there isn't any signal to the injectors. I believe the ecu may have went.
