Did it run before you removed the crank sensor?

the CKP can be hard to seat in the engine properly if not in the exact position it will not run correctly . try to place into this exactly as it was..... disconnect the negative to the battery to make the PCM start from the factory set points . if not fixing it , then may need to be programmed by a GM dealership with the proper diagnostic programmer tool. forgot PUT THE OLD ckp BACK IN !!!!!!!
