Porsche 914 1.8 L doesn't want to start with petrol? Wrong distributor without negative pressure to blame? Options

[Leon.paradise]

Hello I am from Germany and hope that someone from you can finally help me. Unfortunately I have not found anyone who could help me. This year I bought an American Porsche 914, 1.8 L, with 76 HP, which is original and has not been moved since 1997 and has never driven in Europe. It is a project the car has an L-Jetronic injection system. I have already exchanged a lot to start the engine with petrol, unfortunately without success until now. It wanted to ignite with Spray Gas, but not with gasoline. The following components were rinsed out or tried out: new tank, power pump, lines, filters, injection nozzles, ultrasound cleaned, other control unit, wiring harness measured perfectly, new spark plugs. Spark is there. Air mass meter supposedly OK. I have the 7 pin connector. But the car is not running. I have been looking for the mistake since May. In Germany almost no L-Jetronic only drive D-Tronic or carburettors. Question to you, you can also operate the Porsche L-Jetronic with 009 distributor without vacuum socket. Or does he necessarily need an ignition distributor with a vacuum socket. Now I have the distributor (0231 178 009). Did you find out that it is unsuitable? Since it works on carburetors and not on L-jetronic? I have now bought a (022905205S) because it was originally installed ex works? Ask for help and your answers. Greetings Leon

You will want to get the correct distributor for the car. But, with the 009 distributor, the car should still start.

The Ljet is very finicky style fuel injection. If there are any vacuum leaks, it will cause a no start condition. You will need to make sure that all hoses are on, and or capped for the ones you aren't using. Then, turn the ignition switch on and push the flap inside the air flow meter. You should hear the fuel pump turn on. If the pump turns on, we can continue with the next step

Hello, when I turn the ignition key, I hear the pump running and it doesn't stop working. It is new but not original, so the fuel comes up to the injectors. I cleaned the injection nozzles ultrasonically and they work with the appropriate testing device, only not in the car? Greetings Leon
