did you spray under the hood? that would explain it- don't do that- lots of electronic thingies under there- while we're here conversin' let me also say don't ever use jumper cables either- in fact, just give up on the idea of even opening the hood- access for mechanics only- sorry, I didn't invent this 21st Century- it would be different if I had-
