Whenever all injector codes are present and the engine will not start. This indicates the injector driver module in the ECM has failed. I see this a lot. Unfortunately the module can not be replaced. You will need to replace the ECM. I am sorry. I wish i had better news.
Please reply back if you need more help or have more questions. I am happy to assist.
