2000 Mercury 250efi won’t start.
Hello everyone I’m a long time lurker and finally joined after having a problem over the weekend. I have twin 250’s and 1 was running rough I couldn’t figure out what it was only 1 thing came to mind is I had just changed the cdm/coil pack. I swap 1 from the other motor “starboard” to “port” and it smoothed out I put that coil on my starboard motor and it ran poorly. I went to bass pro picked up a new cdm installed it and motor didn’t want to start. I swapped it Out with the port side cdm I replace and that idle rough like before. Is the Cdm’s bad or do I have another issue. Sorry I forgot to add I put the original cdm back on the starboard side and it still wouldn’t start. Help me please. Motor serial numbers 0T015456 0T015420
