no injector pulse

hello guys! just as the title says the injectors are not getting a pulse signal. the injectors get constant 12v, theres spark, theres fuel at the rail but the car isnt starting. ive checked fuses and relays, i still cant figure out what the problem is. any help is appreciated! thanks.
 
if there is a 12v feed then its usually a nats problem mate, loads of nats threads on here
OK man thanks, is it a case of ecu swap or can it be by passed? Or is there some here that can fix the ecu if I was to send it to them. Any info would be appreciated .
