I just bought a brand-new battery for my 94 Cadillac sts I put the battery in and it started right up and I drove it all day then parked it in my drive way this mourning I went to start it again and nothing I mean nothing. It don't even turn over almost like there's not even an engine in it. Plus it has this constant dinging even with the door closed and no key in it, it still has that dinging sound. It's not like a ding-ding-ding-ding sound its more like a diiiinnnggg like non stop until I put the key in and turn it to the on position or diconnect only then it will stop the constant dinging. What could it be? How do I get my car drivable again? Can someone help? ASAP please! (If you live in Salem OR please come help me

I have a 97 cadillac seville sts that will not start.. let me first say what I did .. 2 years ago I had to replace the alt and battery.. which I did about 4 months later (I had company vehicle so I didn't need it). then the car wouldn't start.. I took off what was what I thought was another fuel filter but turns out it was a fuel pressure regulator but no gas was coming out so I took off the connector to the fuel filter but it also shows no signs of gas being pumped. So then I replaced a fuel pump relay and a/c relay and when turning on the car the relays do click over.. so I then proceeded to take out tank to test the fuel pump and replace the fuel filter. I took pump out of the tank and submerged it in a bucket and pump worked.. but I noticed a fray wire on the harness but was close to the connector.. so first question is am I doing anything wrong? And second , which wires should I be testing to test power to pump? Pictures do help thanks

I have some air flow out the small vent that exits the back of the console but it never gets warm. It doesn't appear that the front fan is running at all. Any ideas to help me would be appreciated.


Car won't always start with key but will with remote start button (aftermarket I believe). Engine will die when brake pedal touched unless I set the alarm (also aftermarket) open the door to activate alarm and push reset button on remote. Door lock sometimes open while driving and the alarm will go off while driving. I would deactivate the aftermarket alarm but I don't know how it is attached to the car's system.
