crankshaft position sensor problem

mine is 95 SL1. Last week it suddenly stopped and dint start again. It gives the starting sound but dont start. Mechanic said the crankshaft position sensor is not working. Is it possible fix that thing by myself. How difficult is it. Please help.

its not hard, if you are young and have flexible hands...

it is located above the starter, held in by one bolt (8MM or 10MM?), on the back side of the engine, under the intake manifold. http://www.saturnfans.com/photos/showphoto.php/photo/14836/

I thought I had this same problem on my 96 SL2. It will not start all of a sudden and I just finished replacing the sensor.....still won't start. I have air and fuel to the engine and tested for spark the best I could with a screwdriver on a couple of plug wires. I did not see a spark(I think I had it to a good ground. I used one of the bolts on the top of the valve covers....was that a good spot???).

Any ideas? I need to get this thing running ASAP. Are there any other tests that I could run to see what it is without randomly replacing everything under the hood?

Thanks

I had the same problem with a '92 SC2. First we replaced the Camshaft sensor ($13). It was very hard to find (located behind the starter). After changing the camshaft sensor, still nothing.

It turned out to be the ignition control module. ($180). On '92 models, the ignition control module (ICM) is separate from the coils. The coils mount on top of the ICM.

Before replacing the ICM, I first checked to see that I was not getting a spark out of either coil. The fact that I couldn't get a spark out of either one, pointed a finger at the ICM. (It seemed rather unlikely that Both coils would fail simultaneously.)
