My 2001 Saab 9-5 won't start at all, I tried jump starting it and it turned on flawlessly, but when I disconnect the jumping cables from the battery the car turns off. It can't be the battery because I just replaced it about a 8 months ago. Please help, any information would be useful, thanks.

I had the same problem with mine and it turned out to be the key switch.

You could try tapping the starter and/or having it checked by a mechanic. If the vehicle is starting once in a while, have a mechanic check the Crank Shaft Position Sensor located on the Intake Manifold under an aluminum bracket. The wire to the sensor leads towards the throttle body. the connector at the throttle body is blue. This sensor is notorious for giving out gradually. If this is the problem, seriously replace it as the vehicle could die when driving (i've heard, but don't quote me on that). I owned a 2001 9-3 turbo and the same thing would happen until it no longer cranked. I replaced it when i researched the issue on the internet. The car turned on as soon as i replaced it 8) and did not have the same problem again.

Good luck!

Look for a lose connection at the crank shaft sensor. This is a signal needed for obtaining tachometer as well as turning on the fuel pump.

Change engine coolant temperature sensor/ECT/,located on a back side of the cylinder head. There is two sensors.ECT sensor is on a cylinder head,another is on water metal pipe.
