Re: No start, no electrical, NOTHING
If it were here I'd probably check for fire and fuel first. Fuel is easy, just depress the schrader on the fuel rail and see if anything comes out. Fire can be harder. Usually you can pull a plug, ground it, and see if you get a spark when cranking.
That is generic, I have not had my Crossfire apart to that extent so perhaps someone could comment on the procedure.
