2005 Nissan Murano cranks, but won't start

I misinterpreted the first post. If the dealer said they could run a test and the OP said they couldn’t diagnose the problem, then did not let them run the test (i.e. start to diagnose the problem) then the OP seems to want something for nothing. Not an unusual urge, but it won’t get a diagnosis, maybe just a hunch, which we also can provide here.
