SOURCE: How to sync phone with Saab 2003 / 9-3, with bluetooth device?

Sorry, the original Swedish version of the 9-3 had the bluetooth capability but GM removed it for cost reasons. GM has ruined Saab in many ways. There is no way to sync your phone with your 9-3.

SOURCE: No fuel or power to fuel pump.

If the relay is not getting ground signal to turn on then it sounds like a problem with the ECU this is fed from there. Commonly dry solder joints inside the ECU can cause this problem, they have a tendency to crack around the transistors and heavier load components and also components that are subject to mechanical vibration. He said that the fuel pump relay is located in the kick panel and the ECU is next to this. Id take out the ECU and remove the main circuit board and examine for dry solder joints. If you don't know what they look like its somthing like this

Hope this helps

Hi, I have Saab 9-3 1.9 TID 150 with 113,000 on clock.

Crank and no start. Study these pages and you may be able to identify your problem.......
Crank No Start

It should not be blowing smoke though. Can you advise the colour of the smoke from the exhaust?

If the smoke was whitish in colour this indicates there is coolant leaking into one or more of the combustion chambers which is a bad sign. You did mention the engine was misfiring which is possibly indicative of low compression due to a combustion leak.
If there is coolant leaking into the cylinder(s) this will be via a failed head gasket or a crack in the cylinder head or both.

I have a 2003 Saab 9-3 Turbo convertible, I have replaced the coil pack, the battery, starter, fuel pump, crankshaft position sensor, spark plugs & more, the engine cranks like nobodys busines

did you check for voltage at the coil pack low tension input
this comes from the electronic ignition and the distributer dc setting on a multimeter

check inside the distributer that the little magnet is still in place on the rotor and that the sensor is outputing pulses as it turns over
{you can use a meter set to AC range for this ...}
pull a plug out and place its metal to ground check for actual sparks
if this is there then its fuel ...

2003 saab 9-3 4 cylinder turbo blown head gasket

this is a major piece of mechanical work as you seem to be aware, i would suggest if you feel confident to do it yourself get a workshop manual that will give a step by step guide and the correct torques etc , you wont know if the head needs recon until its off but if it has'nt been overheated time and time again it should be fine , also depending on mileage as to wether the valves need regrinding and new seals , i would do this as well while the head is off as is best practice to carry out further maintenance when the oppourtunity is there also change the timing belt and tensionor ,you can probably hire the correct tools needed as buying would cost quite a bit to be used only once so there is a lot to consider so i wish you good luck and keep me up to date please.Also bear in mind the age and condition of vehicle against cost of repair might be better to trade in keeping the head problem to yourself!

2003 SAAB 9-3 When I stick the key in the ignition, I do not hear the unlocking sound on the steering column like I usually have heard in the past. The Key will turn and all electronics work, but the car...

Sounds to me like the ignition switch itself,or the interlock device,might be worn out.Is it a straight shift ??(Sometimes on SAAB's you have to put the vehicle shifter in reverse to enable starting,I believe ??)
