The car was carbs and the fuel pump was on constant when the key is on.
I am trying to put it back to factory settings. As far as I understand in djets, when the key is turned on, there is a pulse to turn the pump on for a quick second then once the car starts the ecu keeps the power on to keep the fuel pump running. I am not getting that pulse. The relay clicks and I even switched the relay. I noticed that the PO modified the connectors on the relay board for the carbs. (See pics) please help me she's some lights The car is a 1.7 djet year 1970 Thanks Attached thumbnail(s)

Interesting, pin 11 (brown white wire) from the 14 pin connector is the same tract as this green/yellow wire pin 10 of the 12 pin connector. This is the wire you had in question. The brown white wire has its insulation stripped for whatever reason. Both wires serve no function, if I'm reading the diagram right and if your car is indeed a 1970.
This gives me a great idea for my car. I need to feed a wire for my trunk solenoid to the dash board. Since pin 11 and pin 10 are not being used, I could steal that wire for a clean trunk switch installation. Towards your problem, you say you hear the relay click, or is it clicking from you testing it? I'm assuming you removed the carb and already installed the brain and the other Djet FI stuff? |
