Are you sure its injector ? have you checked spark and fuel pump first ? (sorry always start at the begining )
fuel cut in boot?
spark at plug ?
pump priming.?
Have you changed anything latley ?
Fuel in car ?

DON'T check the earth at the injectors with a test light, this may damage the injector drivers in the ecu.
The fuel pump is controlled totally by ecu output so if it primes then ecu is getting power, if no live at the injectors then check the main power relay is outputting, this ends a live to the ecu and the same relay sends the live to the injectors, most likely a dodgy wire.

I personally would be looking at other possibles other than a whole injector loom gong down when it hasn't been touched and the car was runing fine. one assumes the car has an immobiliser other than standard key code system ? . do you know were the cut's are for it and have you tested them to rule it out? . have you tryed another key incase the chip isn't reading correctly ?

All i can suggest is that you check your earths are spotless and start checking the loom back to your ecu. Also may be worth getting hold of anther ECU to plug in and just rule it out ?
