You need to check to make sure the injectors are getting power. You need a noid light. Most parts stores will lend them to you. All you do is unplug an injector, plug the noid light into the power supply side of the wiring, and it should pulse on and off when power is sent. If it doesn't get power, chances are you have a wiring issue to the injector or the PCM is bad.
