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? |

Well, I started back at the beginning of our testing.
After taping off the positive lead to the coil, I tested as follows: - Ignition switch on - Negative lead from multi meter on battery - Positive lead touching the following: 88z - 12 volts 88a - 12 volts 88b - 12 volts 88d - will run fuel pump with 12 volts jump wire from positive terminal 86c - will get 12 volts with jump wire from negative battery terminal |
