Thanks Frank,
I found a wiring diagram for the car, trying to read through it.
Could the switch box TSZ 8z be bad? (the ignition box # 0025452632 on the left side where the green cable to the distributor plugs in).

So far I can find no reason why the ignition should not work but still no start.

I'll probably go back to the beginning.

- Test fuel pressures (system pressure ) and check if the fuel pump is running during cranking. Fuel pump is running if I bypass sockets 87/30 when relay is removed)
- Test for spark again.
