2000 Saab 93: intermittently wont start..fuses..cranks

Customer Question

I have a 2000 Saab 93 that intermittently won't start. The fuses and fuel pump seem fine. It cranks over but won't fire. This is my first Saab so I don't know much about repair on it. I have been repairing cars (for myself) for many years though. Thanks.

Well if your certain you have fuel you have no spark,this is usually due to 1 of 2 things.Bad Crank Sensor, or a bad D.I. Cassette (COIL PACK). The easiest way for you yourself to tell which is go to an autoparts store and buy a tool called a noid light. The noid light is a small test light that can be plugged in one of the 4 fuel injector plugs.When the car won't start, hook up your noid light and watch it while someone trys to start.If it flashes you have crank signal indicating probably a bad DI.If it doesn't flash you probably need a crank sensor.

Thanks. One other questions. Will either of the two parts you mentioned be more apt to cause the car to sputter and stall at intersections?
Expert:  Pete NelsonJr. replied 8 years ago.
Usually D.I.'s will be more likely to cause that type problem.Crank sensors usually act up when trying to restart the car when its warm.

I have the crank sensor on the way. Where is it located on the car?

Expert:  Pete NelsonJr. replied 8 years ago.
Its down under the exhaust manifold and turbo on the engine block.It's like a 25 or a 30 torx I believe.Just one little bolt.and you wiggle it out and wiggle the new one in.Make sure your old o-ring comes out, if you end up with 2 o-rings in the hole you'll have a leak.Hope this helps.
