So when you turn the key and engine switch on does the fuel pump prime? Does the check engine light come on then go off? |

no.... it does not prime... or run , checking the power both sides (power and ground ) show power , less on the ground side , If i check it straight from a battery it runs with power/ ground .. there is no check engine light showing . |

Turn the key on, when you flip the kill switch from stop to run, does the check engine light come on for a few seconds? If not, the ECM is not powering up, and as result it isn't telling the fuel pump to activate. |

Check to make sure the ECM is getting power. Pins 1 and 2. The bank angle sensor could also be bad or stuck or just not installed properly. You can check it by measuring the resistance between pins 1 and 3 on the sensor itself. If its high than 1 megaohm its bad. Also check the voltage on pins 5 and 6 on the BAS connector. |

Just to make sure you checked on the black connector? Did you check the ignition fuse? |
