I'm having serious problems starting the engine (no matter if the engine is hot or cold).
It happens randomly. Some days it starts normally and others it takes a long time to start.
Everything in the board computer seems to be OK. The battery is brand new.
All services where made at Saab (it has 137.000km).
Does anyone have a clue about what the problem is?
Thanks in advance,
Ok, finally I've found the solution...
This problem (at least it worked with me) was related with the diesel return tubes... With time they deteriorate and let air going inside the pump, since the are under vacuum, and make the start up very difficult.
To know if this is really YOUR problem: park the car with the engine faced downhill!! If it starts (like mine), then substitute the diesel return tubes (I payed ~100€ for this, at a Saab garage).
