We're the glow plugs removed for the 4 or 5 months ? It's definitely possible there is some corrosion on the cylinder. This happened to me. I remedied it by using on blaster or other agent into the cylinders via the glow plugs holes and just worked the engine back and forth.

It goes without saying but you're going to want to blow all the crap outa the cylinders before you even think of putting those glow plugs back in there unless you want a grenade.

Will the torque converter spin freely on its own? Any chance it's binding in some way with the flex plate ?

Edit- I read the thread again, I see the TC was pushed back. The flex plate is correct size compared to the old one?
