I have a 1992 saab 900S 2.1 non-turbo engine, The car has been running fine the psa few months, recenlty it will not start, I put the key in the iginition turn the key, the lighs on the dash comes on then nothing, the lights onthe dash go out and nothing, the car goes dead. I put in a new battery check the battery cables and ground on the negative side. visually all looks ok. I think it may be the iginition switch, but want to be sure before I have it replaced Thanks

The issue with starting systems is that there are many things that may be wrong with it. It certainly sounds like an electrical problem. I'm going to give you a way to check to see if it is actually the starter itself that may be bad. if you can physically reach the starter(on some you may not be able to) LIGHTLY tap on it with a hammer and then try to start it. DO NOT hit it very hard because this may cause the starter to become inoperable if it isn't already. if you turn the key and the batter just gets drained dead then I would sound to be a starter issue as well. These electrical issues are looked at by trained professionals in legal service shops.

As a licensed and certified mechanic I would highly recommend you have it tested before you start throwing parts at it because that may be VERY costly.and time consuming. when properly diagnosed you can save time, money, and a massive headache.

Hope this helps you out!
