W115 280 won't start need help and diagrams

hello guys,
i will try to explain as much as possible.
bought the car like this, was told it had a problem, supposidly the fuel pump had gone, tested and no power coming to fuel pump.

i then check for a pulse at the injector plugs and nothing, tested the trigger switch in the distrubitor and it seems to be working.

i then undid the connector going to the ecu and there is no power anywhere.

it is sparking and when cranked it would momentarily start but not keep running, meaning that the cold start was working.

there are extra wiring harness and a switch inside the cabin suggesting that this car was once fitted with a lpg system.

i really am in need for some wiring diagrams for the engine wiring harness and ecu connector.
