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 |

First verify that the main fuse is working. This feeds all the relays, to include the fuel pump relay. If the fuse is good then continue with the next paragraph.
Try removing the fuel pump relay and check for voltage on socket 30 with the key on. There should be 12v present. If not then there's a board problem. If there is 12v present turn off power place relay back on board, turn key on and check for 12v on pin 13 (harnest near the firewall/this "should" be the original 12v lead to the pump). If 12v is present then you have a bad wire or ground. If 12v IS NOT present, you then have a bad relay. Try placing another relay in its place to verify bad relay. Good luck. This is based on the diagram I placed eariler. |
