iod fuse = ignition off draw
it is a fuse that you can pull if your car is going to set for a long time and will not run the battery dead. Most new cars come with it out from the factory and tech installs it when doing a new car prep.
it will not affect whether the car starts or not.
does the car start and die in a couple seconds?
you car try leaving the key in the on position for 30 minutes and it might reset itself.
of course with a battery charger hooked to battery.
i have seen it work a couple times myself.
wcm = the style of fuse if memory serves me.i do not believe that the crossfire comes with iod fuse
