Question about 2000 Chevrolet Astro
Here's another head scratcher..
What would cause my engine to not crank easily? I feel something is putting a strain on the engine from inside. I've tried turning the crank manually using the pulley bolt and it won't turn. I've tried a strap wrench on the balancer and it still won't turn. The only way I can get the engine to move is to crank it normally with the starter. However, it turns slowly and starts to smoke if I try it too long. The starter was checked at AutoZone to be just fine. I bought a new battery and nothing changes. I have fresh oil in the pan after having to replace it due to a coolant leak - which is why I'm working on the car now. Wouldn't everything get lubricated internally after a multiple cranking sessions? Oh, I did remove all spark plugs at one point and it spun easier, but I still couldn't crank it by hand or by using the strap wrench. What could be causing such a drain on the engine while cranking?
If engine has been cranking a lot & not actually running, there's a real good chance cylinders are dry. Also, I need to ask where coolant was/is leaking as you may be experiencing some hydraulicing in cylinders due to coolant leaking in, but I hope if that was the cause of your coolant loss/leak, that it has been remedied. Another possibility would be plugged exhaust causing too much back pressure.

Sounds like main bearings
if you can remove oil pan and grab piston rods one at a time and try to rattle them around look for metal shavings in bottom of pan
