Re: 258 w/ feedback system headache
I would check the battery. They can often die without warning. Do your lights work? Just what kind of "wash" was this? Is the starter turning the engine? Or is just dead, period?
Check your ignition module and your battery leads. Do you have a voltage tester? If so, you can use it to see if you are getting voltage at the various ignition points.
I would start there.
Hope it helps.
