92 century still not starting in the morning

Seems to have something in common with how cold it is outside. I replaced the coils and ignition module and still have the same problems.. How difficult is the crank position sensor to change and any tips on doing this... I cant wait till it gets warm out to be able to start my car.. Im gonna get the multimeter out today to double check the ignition control harness from my previous post. but every day its looking more and more like the crank sensor

Wouldnt start this morning, but now that its 43 degrees outside it started right up. i dont know what to do!:banghead:

Okay here is the deal. The car wont start. but this is what i got on the multimeter

From left to right on harness

Pink 12v Run position
black 12v Run position
white/black 0v Run position

1 N/A
2 N/A
3 N/A
4 N/A
5 N/A
6 0v grounded, 12v Positive bat terminal Key off, Voltage drops when motor is bumped
7 0V grounded, 12v Positive bat terminal Key off, Voltage drops when motor is bumped

I have already replaced the coils, and ignition module. i really only have a hard time when its cold out but otherwise it runs fine once i get it started. When it does not want to start i have no spark off the coils. Any help would be appreciated

Any ideas would be appreciated... Im thinking about replacing the crankshaft sensor, because that seems obvious, but for some reason i dont think its the problem because its to obvious.I have good fuel pressure, injectors are firing, engine is turning over. No Spark when ouside temp is 45 or below. Starts and runs fine when the weather is just a little warmer. (also have a new ICM and coils) Any suggestions on how to set the crank sensor clearence when reinstalling so i don't destroy it...(id prefer not to have to buy the $600 GM tool)
