99 sls electrical issue

[billtoole]

I woke up this morning and the following items do not function. Power Locks, Gas Guage, Remote Trunk, Remote Gas Lid. Probably some other things not working but that is all I have found so far. All worked yesterday. Looks like these items are covered by multiple fuses. All look good. I changed the accessory relay under the hood, still not working. Kind of a pain not to have a gas guage, the computer will not even gice me a number of miles left. Has anyone else run into this one??

not ignition switch. Start with checking fuses. That may be a fun electrical diag that would have to be looked at in some length.
