Fuel injectors still not pulsing fuel, Well I've replaced the MAP sensor, still no start-up, where do I go next?

Answers :

If injectors don't have power, check the signal from the PCM. They have an internal driver circuit for grounding. There is also a relay. If the relay goes bad, it will disable the injectors from getting a signal.
Other sensors you can test that control fuel is:
Oxygen Sensor, TPS, Airflow Sensor, Air Intake Sensor, and surely the camshaft position sensor. And of course the MAP.
You can test any sensor with a meter. I would start with power coming from pcm.
