Hi. I recently bought a '74 1.8 and am looking for help to get it running. It has the original fuel injection and ran late last year according the previous owner.
Here's what I know after reading many posts in the forum and working on it. Thanks to everybody who contributes, I couldn't have gotten this far without your help. - The dual relay is bad I believe. After wiring it all back up, there is power from the ignition to both the start wire and run wire but no power to the fuel pump. I'm jumping the pump currently to test - All relays in the board work - Fuel pressure gauge shows 35psi on startup. I didn't install this gauge but seems to work ok - Will fire with starting fluid I'm thinking I must be pretty close and suspect the car isn't getting fuel but the gauge shows pressure? |

The resistor pack should look similar to this:
Once you disconnect the connector to this device, set your meter for resistance and put one meter lead at the center pin (on the connector leading to the resistor pack). Probe the outside pins with the other meter lead. You should get a pretty low resistance on those four pins. These wires are frail and tend to break. It would be nice to rule this out before diving into a more complicated test procedure. |
