Yes that's correct. Crank pick up is the crank pos. sensor. Although knowing these 3.8s, the sensor itself was rarely the problem, it was the crank pulley that was badly manufactured and split in two more or less after a few years and that left the tooth gear used with the position sensor free as a bird and not giving any signal to the sensor. So either way, they are in the same area so easily inspectable both at the same time and definetly where i would start looking.

SOURCE: why is there No Spark in a 1991 Buick Lesabre

ECM would be the next part. Check the number on it . If it has the number 1228253 replace it anyway because they give a cutting off problem. Clean battery cables all three and replace bolts too.

Can position sensor, maybe, or it might be called a pick-up coil. This sensor is needed along with crank position sensor for computer to determine spark timing.
When you get it started, and if you still have the up and down idle, check for an intake manifold leak.

No spark can be caused by a bad crank position sensor, or a bad pick-up coil inside the distributor, especially if you can't find a signal to the coil with key on. You could also test the coil, or try a known good one. There is a test procedure for the crank position sensor, but you'd have to locate a repair manual for it. I think it's just running a resistance test across two terminals of the sensor harness connector with an ohmmeter. My son's Jeep had a bad pick-up coil that shut it down, and no spark.
Once you get it running, and if still hard starting, check the fuel pressure.

If it does end up being a short due to a break in the insulation, you can get a replacement wiring harness from a junk yard or even order one and replace that section of harness. I doubt this is your problem. When you get a random misfire or a constant misfire on one cylinder that is not related to the coil or coil pack it is usually a problem with a Crank or Cam position sensor. You say it happens consistantly when it rains, that tells me it is most likely the Crank Position sensor and to be more precise a problem on the crank where that sensor is mounted that is preventing it from detecting the #4 firing position. Remove, clean both the crank and the sensor with clean rags and inspect he sensor wires for breaks or contact with moving parts. If any are found replace the crank position sensor.

I also have a 2003 2.2L ecotec manual transmission.I have changed plugs,coil,map sincer,still have a misfire problem,i think somthing is wet inside but what that might be i don't know.Any suggestions


I worked on another fuel injected vehicle and found that it had an injector problem which had caused the check engine light to com on telling me that I had a random misfire.I did the same as you did and changed the knock sensor ,the crank position sensor and the cam position sensor only to find out that is was a distributor and injector problem.I would recommend that you test your cam and crank sensor and make sure that they are working properly And if the sensors are good then I would check my fuel system including the injectors to make sure there are no bad ones.
