I drove a Cadillac a few times when I was in my teens and wanted a Cadillac ever since, then last year I brought a 1997 STS. I love the car, it's a hoot to drive very powerful and comfortable to drive. It's in great looking condition but my disappointment comes in with the reliability.The one time I had it any distance away from home my wife and I was on a bus. trip and after coming out from the hotel when we checked in the alternator quit this was after I had replaced the starter but before the headlight control module gave out. last week we went to an anniversary dinner with our children and when we arrived at the restaurant the security problem code came up and two days later it refused to start. It's at the garage now with a fuel pump problem that the tech found while trying to fix that security code problem. I am sure when I get it back something else will go on it. I love the car and love to drive it's a real beauty.
My fuel pump keeps going out on my 1997 sls can you tell me what the tec said about the fuel pump.I cant figure it out there are no codes coming up on diagnostic.replaced fuel pump it started then ran ,i shut it off let it sit for an hour and it has no fuel in fuel rail or fuel pressure regulator and will not start.
I had similar experience couldn't figure out why no fuel. After new pump and cleaning and going over almost all grounds and electrical. We figured out it was security system not recognizing the chip key so it shuts off fuel pump as a immobilizer. Is something to look into was alot of headache and head scratching before we got it figured maybe this helps
