On my 2004 S430,

There is so much fuel dumping in Cyl 2 it is locking the motor up upon starting.

I'm assuming the injector is bad but I would like to rule out the computer.

The confusing part that I have is I see mis fire codes for cyl 1 & 2 & 3. Now can a bad injector cause mis fires in other cyls? Maybe a build up of fuel in the manifold can leak in to other runners?

Can the SDS help diagnose a bad computer? If so how?
