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 |

I'm not a fan of hot wiring Rob. The relay board looks a little daunting but it is relatively easy to troubleshoot and fix. Most of the time it is a relay or the fuse. I've also heard of the fuse holder needing to be fixed. If you spend an hour trouble shooting there you should be able to find the source of your problem. Be happy to talk you through it. A cheap multimeter is all you need.
There was thread recently about a fuel pump that would not spin. Turned out to be stuck brushes. It would be interesting to see if that is the problem with your pump that wont hum. |
