Sorry I didn't get back quicker. I didn't receive notice that you replied. Continue this thread so I can respond. Regardless, do what fixitmr said. If you can, see if you can rent a noid light from the parts store. It is made for checking injectors.

You need to check for power to the injectors. If there isn't power, you need to first check the wiring to the injectors for continunity and then trace it back to the PCM to locate where the power is lost. It could be a bad connection or correded at the PCM.
