if your not getting current to your fuel pump, its probably not a sensor, the car doesnt sense whether or not to send fuel, it always sends fuel when its on, so i would check a fuse or a relay, however if you are getting fuel but not in the right amounts, i would suggest mass airflow sensor, throttle position sensor... etc, and if you arent getting a spark, i would check the coils, if you arent getting either i would check the ECU
