2000 s10 the original engine seized i purchased a used engine i believed is out a Chevy astro year unknown is there a chance the reluctor wheel is not same from the original
Expert:  Jerry Newton replied 6 months ago.
If all of hte electrical connections were the same between the two engines, then the reluctors are the same. P0336 says you have missing CKP pulses. Is there actually a reluctor in there? Remove the sensor, stick your finger in there, and make sure you can feel the reluctor.
Customer: replied 6 months ago.
ok i will check if reluctor is there.
Expert:  Jerry Newton replied 6 months ago.
Reman and other engines come without a reluctor, it's possible that someone removed yours for one reason or another.... who knows, stranger things have happened. It's definitely worth checking, though, to make sure it's there.

before i pulled the old engine out the crank sensor connector was in bad condition the wires were strip and touching can these cause a short in the ecm
Expert:  Jerry Newton replied 6 months ago.
No, the PCM is fairly well protected against that sort of thing. You have a scan tool, does it read live data? If so, does it show something other than 0 rpm when cranking the engine?
Customer: replied 6 months ago.
reluctor wheel is there but i couldn't get rpm cause of the of the dead battery but when i was down there i notice the timing cover was about 2 cm off not sitting flush with the oil pan can this cause the crank sensor not pick up signal from the reluctor wheel
Expert:  Jerry Newton replied 6 months ago.
How is the timing cover not sitting flush? It fits on locator pins when you install it, did it fit where it belongs when you put it together? I have seen crank sensors back out of their holes just a tiny bit (1/4") and cause the engine to not run, so yes, if there's something funky about that timing cover, I'd square it away.

timing cover sitting flush i plug in the scanner and theres no rpm
