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)

We solved the issue with the fuel pump. The pump primes fine. One of the relays was bad.
Phase 2 : We try to start the car, it cranks but does not start. Timing and TDC are checked and spot on, the coil will not spark. Just to confirm. The thick black/ purple is on the positive (+) side of the coil and the small black and condenser on the negative (-) With the ignition on, I get 12 volts at the + / black/ purple wire with the ignition on, I have ground on the negative side of the coil, when I crank, the negative side of the coil switches from ground to 12 volts positive I replaced points and condenser, Same issue. |
