I've put my engine back in the car and want to confirm the FI fuel routing. I've looked at PP/Dave Darling's diagrams, but would like confirmation:
1. large (9mm) plastic fuel line from firewall connected to fuel filter 2. fuel filter connected to fuel pump at (S-suction) connection 3. (D-damper) connection on fuel pump connected to fuel rail on passenger side, rear connection 4. (R-return) connecton on fuel pump to Y connection 5. Y connection to small (7mm) plastic fuel line from firewall 6. Y connection to fuel pressure regulator 7. fuel rail on passenger side, front connection, to fuel rail on driver side, front connection 8. fuel rail on driver side, rear connection, to fuel pressure regulator 9. fuel rail on driver side, middle connection, to cold start valve. Also, I'd like confirmation on the electrical connection to the fuel pump: 1. black/red wire to the + side of fuel pump 2. brown wire to the - side of the fuel pump If I wanted to test the fuel pump outside of the car, I should be able to connect a positive wire to the + of the fuel pump, then to the + side of a battery, then - fuel pump to - battery. I could then connect the (S) fuel line and place in a container of gasoline. Then place the (D) and (-R-) fuel lines into an empty container. When I connect up the electrical lines, I should get the pump to hum and run fuel through the pump. Also, if I turn on the ignition, I should be able to get voltage across the black/red wire and the brown wire, correct? Finally, has anyone successfully found a shop that can rebuild these fuel pumps? -- Rob |

Steve, thanks for the reply. I forgot to add that yes I'm working with a '74 2.0l engine. Earlier this year I bought a FI fuel pump that supposedly worked. When I installed it and added power, I didn't get any humming, so I removed it and connected it directly to a battery, but without any luck. So, I tried another pump, hooked directly to the battery and got a hummer... (IMG:style_emoticons/default/biggrin.gif) . So I connected everything back in the car and turned on the ignition, but no hummer. Since it appears that I'm not getting any power to the pump from the electrical system, I'm going to hot wire it. I'll try jumping the relay, but if that doesn't work, I'm going to run a hot wire (switched) from the fuse panel.

So I connected everything back in the car and turned on the ignition, but no hummer. in order for the pump to work correctly, the FI brain must be hooked up and plugged into the relay board! and you also need the pump relay in the board and the the fuse on the board.
