My 1993 LeSabre has an engine trouble code 17 reading.

Manufacturer Specific Definition:

code 17 : crank signal circuit OR ECM fault crank position sensor circuit (3.8L)

Here is what happens

I can be driving than suddenly my vehicle will just stall. I will have to wait for 5 to 30 minutes before it can start again. on other occasions the car won't start at all, the engine just turns and turns. this happens out of the blue. sometimes it will occur 3 times in a day and other times it will happen every few weeks. So my question is should I think about A. Checking the wiring from the Crank sensor to the ECM. B. More likely replace the Crank sensor. or C. Replace the ECM. Please help.
 
Crank sensor

If you compare the cost for replacing the crank sensor to the effort of continuing with the problem by checking wiring and so on,I would replace the sensor first! My 1987 Park Avenue had the same behaviour and after finding out that there were no codes for crank sensor on 1987 I replaced it,easy job and car runs like new!
Good luck!

Crank Sensor-good news

My buick is running great now. It was nothing more than my CPS. Thanks
 
just a little tip for low buck diagnostic on this type of sensor problem: put the car somewhere safe and wait for it to quit, then spray the suspect sensor with cold water, likely, if the sensor is faulty, getting cooled off will make it work again. (this procedure has never failed me)
