No codes at all, when the key is placed in start, the dash lights up normally, aside from the low battery indicator. I actually just had a shop look at it, I broke down across the street from one. I don't have the money to start replacing parts blindly, and after I asked them to check the fuel pressure, they agreed with me that it wasn't up to snuff (40psi), and that the fuel pump was bad, the whine was crazy loud, which was why I kinda felt that's what the problem was. There weren't enough symptoms of the ignition switch to justify a blind replacement, since my dash still worked fine, but the low battery indicator did pique my interest. The guy I bought it off of is pulling a working fuel pump off of a parts truck for me. It's a Bosch less than a year old, so I expect to get some mileage out of it before I have to put in a real deal ac delco replacement. At least it's not an Airmax, or some other cheapy pump. I just need the thing to run long enough until I get money saved up to fix her up right. I was just shocked that it died so soon.
