yeeha68's post in Random stall that cranks but wont start for a random period of time. was marked as the answer
Well I think I have solved the issue. It looks like it was indeed the Crank Position Sensor (CKP). And in reply to JayUSA123-You are correct on your Ohm readings. My old one read 10k on pins 1 and 2, while the new one read .9k which is right in range with your readings.
And now a word of caution to everyone attempting this replacement. Removing and replacing the sensor is not a big deal. It took 10 min. to get the sensor out, and it should take less to get the new one back in. However, you are working a good distance away from the sensor and using a long extension on a socket to remove/replace a single screw. Heres the fun part...as I was negotiating the screw into the hole it dropped and disappeared. After a few minuets of searching I realized that just to the left of the sensor there is an open inspection port for the flywheel. You cant see it, but you can fit three fingers into it. Its a half circle shape about the size of a starter hole. Anyway, the screw easily disappeared into it and was unreachable. Im embarrassed to even admit this, but I hope this knowledge will help someone else in the future avoid this trap.
After reviewing old pictures from a previous build, I assumed the screw fell into a small pocket cell and was safe from doing damage to the transmission. That feeling lasted for about a week until I came to terms with the fear of a lose screw in the clutch. The last thing you need is a screw catching on the flywheel and jamming at high speed. So for my own peace of mind, I decided to drop the transmission and retrieve the screw. For those of you who have done this, you know just how fun that was. Oh well, it only took a day to do and gave me a chance to get a real good inspection in order.
As it turned out the screw was indeed in a small pocket cell (see photo attached) and probably would not have caused a problem, but in the end, Im glad that I took the time to retrieve it and avoid future damage.
So long story short...Dont Drop the Screw into the Inspection Port! :oops:
