Diagnostic help

WARNING: This page is about a different car, the 2003 Saab 9-3 and 2002 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

Most functions that can stop the engine from starting are monitored by self-diagnosis and therefore generate diagnostic trouble codes if they malfunction. This fault diagnosis therefore applies to faults that are not monitored but can prevent the engine from starting.

Make sure the fuel pump is in working order and delivering pressure first. Then, check the CRANKSHAFT POSITION SENSOR , ignition discharge module and spark plugs.

Functions in the diagnostic tool related to the fault:

Activate fuel pump relay.
Activating ignition triggers.

See also the description of activations under "FAULT DIAGNOSIS, GENERAL " for more information.
