No Spark (and yes I checked everything according to the check list)

[udm328is]

Ok, so I checked everything according to the check list and still no spark. I have a Mercruiser 5.0 with the Thunderbolt ignition and after going through everything on the check list I am still stuck, Any ideas? It seems I have a fuel issue as well as it seem nothing is sparying out when I pump the throttle, but I need to get someone to look when I do it to make sure but looks like it is still dry when I do, but I'll get more into that when I read up on that I guess unless there is any chance the two issues are related.


As always thanks in advance for any help and suggestions,
Eric

What check list are you referring to?

Got a serial number for your engine handy, all carbed engine have had Thunderbolt ignition systems since the mid 80's.

SN is 0D712714, as far as the check list I was speaking of is the one for troubleshooting engine starting system and did all those checks and everything checked out

The starting system has nothing to do with spark, only making the starter turn the engine over. You should have a Thunderbolt IV system, try this check list for spark problems.
