I tried to start my car today. No go.

For those of you familiar with my last post (Bosch Electronic Ignition), I wired according to best advice / appropriate wiring diagrams, replacing my original ignition system with a Bosch electronic system from a 1975 240. The car won't run at all. Any help at all with a logical way to go about diagnosing the problem would be seiously appreciated!!

The car turns over fine. I have newly rebuilt SU's and by the smell of things they are getting (and giving) gas just fine.

There is absolutely no hint of ignition. I put a timing light on the spark plug wire while cranking and got no strobe at all. It appears I don't have any spark.

The system is wired as follows:
black to ground
white to original (B-18) distributor (-) terminal
green/brown to distributor
blue to fuse box off switched 25 amp fuse.
There were two brown wires (one in loom with the white, and one going into the resitor with the blue wire). I took the resitor out and sent both brown wires (via a diode) to the one and only small terminal on my original starter.
All connections are tight and solid. The fuse box has been rebuilt by SWEM.

Now, the system came to me from eBay so I soppose anything is possible. I don't even know where to start to figure out what is wrong.

Any suggestions (or alternatives for electronic ignition with new distributor) much, much appreciated.

Many thanks.
