The Crank fuse is ECM related. Any reference that said it has to do with the starter cranking the engine is incorrect.

OK. Thanks. I'll keep that in mind. I have an old ECM which would quit working when it got hot. I already tried putting that one back in and it didn't help, but that was before I found the blown crank fuse. On the other hand, I don't seem to get 12v to the fuel pump connector by the fuel tank when I put 12v to the test lead at the fuel pump relay. That could not be due to the ECM, so I'm still baffled in general.
