You're saying there is a spark at the plugs or the injector is working ?

If the injector is not pulsing, check the fuses.

The injectors are controlled by the Powertrain Control Module (PCM), which is unlikely to be faulty and is not cheap to replace.

$ome $imple fault finding might $ave you a wad of ca$h.
