I got my 2.0l 4 cylinder installed. The ignition is functioning. The fuel pump never turns on. I wired it directly and verified that it pumps and builds about 35 pounds. What do I need to look for that would prevent the pump from running under normal operating?
What all wiring connections effect the fuel pump in the engine compartment and under the dash? Thanks James |

Verify where the wires go. One should supply power, the other should be grounded full time.
In stock form, the fuel pump is run by one of the relays on the relay board, and draws its power from one of the fuses on the relay board. Is all of that stuff present and OK? --DD |

The two center relays are present on the relay board. |
