injectors aren't getting a pulse signal. why??

With the ignition switch on, check for voltage at the injectors. The injectors get a steady voltage, and pulse through the ground circuit at the ECM. If no voltage, check the 30A AM2 fuse under the hood. Then check the injector resistor.

Also, check the TSRM for EFI diagnostic procedures.
