I have a 4.3 mercruiser with no spark. Do you have a test procedure for the sensor in the distributor and one for the module?
I'll insert the Mercruiser manuals "flow chart" instruction on testing this system. It is mainly a process of elimination following a few very simple electrical tests.
Best of luck.
