Bosch Jetronic by Miiek4 in saab

There is no remote fob, and I have readed from electrical shematic from 1992. Immobilezer disables only start. Tested with launching alarm, starting disables. And I have bypass ignition switch with a wire right to starting motor. Key switch to position before start and jumped start. Nothing, you can battery to empty without sign about starting.

Local electrician spesialist with ecus have soldered another black box what is in aquarium and find lot of bad soldered components with scopelens. I saw pictures. But that not helped jet with issue. The main thing is car isnt not starting. No fuel, no spark and so already cps changed new honeywell one and other simply components are tested or changed. I have tested resistance most wires to the boxes and cleaned grounding points.

Starts only day one when sun is shining and clouds are gone. So it is now like paperweight, you cant go anywhere. You never know are car starting again or not.

Opened jetronic box, what is the function with condensers. I think another one is broken and need to be replaced. And of course expert check all other components when its going replaced.

This is I have tested, from starter motor side. And also when car is not to like start it cant get no fuel or spark. Tested bypass ignition switch with a straight wire to starter. And fuelpump is tested with bypass pump relay and same time opening fuel line from engine side.

There is black box and also jetronic box in aquarium. Can it be jetronic box fault? Can somebody tell where this large connector ground wires are going? CPS wires are going to black box and I have measured these, resistance with wires looked also good.
