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 |

It appears as though the PO wired the pump in wrong. So I'll rewire from the firewall to the relay board. Also, the ground side of the fuel relay coil that goes to the four spade connector is not grounded and so the fuel relay does not engage like it should. When I grounded it and got the relay to engage and got 12v out on the fuel pump terminal the pump still did not turn on ergo pump wired incorrectly. The pump was rewired since it is installed up front like the 76 but installed on the 72.
I could get the engine to start tonight and when holding a fast idle it would hold stable for about 3 seconds and then start to stall and then try to rev up again and then start to stall again. Ideas? |
