I know this may be reaching since it sounds like you know what your doing but you did get the plug wires back in the right order and check all fuses right?

 

all plugs in and wired to the best of my memory correct

distro:
m
6 5
4 1
2 3

cylinder:
6 5
4 3
2 1 right?
also checked my ckp and there was no voltage going to it so i researched that prob and people were talking bout a master fuse (couldnt find one) but i did descover that there was a main plug above the brake booster that had somehow come unplug so that fixes my electrical problems but now its still not wanting to start any advice

also a video of it cranking

 

got her started heres a video

 

Yeah that sounds like a lower end knock, if you're lucky its a loose torque converter bolt (happens sometimes) but from the video it sounds like a bearing.

 

yeah after talking to my dad about it and looking up videos of people that have had the same problem bad rod bearing/rod knock is the new conclusion i have come to not that hard to swap it out unless theres crank damage i know theres no head or piston damage checked them all when i had it all apart before the one thing thats gonna be hard is pulling the pan to get to the rod connector (crossmember is perfectly in the way and to the best of my knowledge its welded in )

any advice on how to easilyish pull the pan without pulling the motor?

 

I believe I read somewhere on here that the only way to get the pan off a 4x4 is to pull the motor because the oil pickup tube gets in the way or something.

 

Unfortunately an easy way to get the pan out with the engine still in does not exist. You have to drop the differential or cut out the pan

 

mines 2wd lol i wish it was 4 wheel though i used to get stuck in places really easy

 

Oh!! Well in that case you are lucky. I believe jacking the engine up 2" should work (i wouldn't go more). Search around on Google "2wd blazer oil pan removal" should bring up threads from here. Ive seen them before

 

This one reads like its a 4x4 but it might help.
