Alert me when someone posts in this thread:

Hi Navid,

First, what about your clutch safety switch? Do you have any indication that it's not the wiggled key but a wiggled clutch pedal that allows a start?

Then I would go the the end and work backward. Wire up to test for power at the starter solenoid. Disconnect the battery, and wire a test lead to the small solenoid energizing stud from under the car. Be careful not to create a short to the positive power stud for when you reattach the battery. If you have power at the solenoid every time you turn the switch, but no crank or start, it's the starter & solenoid that are mostly not working. If not, then the problem lies elsewhere.

The signal at the fuse is not enough, because it powers a relay, which also gets a signal from the imobilizer circuit in addition to the ignition switch. That relay is #517. Use WIS Online (Starter, diagnostics) to see circuit diagram, though WIS Online has a few quirks in where you find the diagrams. The relay block is to the left of the steering wheel behind the headlight switches. If that relay is working, then the starter solenoid or loose leads are the likely bad actors.

The most likely problems to me appear the starter solenoid, followed by starter brushes, followed by ignition switch. Don't rule out the switch, because in parallel to the 'standard' circuits there is the SAAB Imobilizer circuit, and if the switch messes with its voltages . . . .

There are 9-5 owners who have cured erratic starting by a simple removal of the starter and thorough cleaning of the solenoid and its contacts plus the Bendix mechanism. Or maybe new brushes for the motor, or at the limit, a complete starter.

Hope this helps,

Mark in Marine
