Engine won't turn after replacing timing belt
91 Civic Hatch DX 1.5L Egine
I just finished replacing a timing belt, drive belts, water pump and spark plugs with all OEM parts. I started the car but the engine won't turn. This is the first time I have ever attempted something like this beyond checking oil and coolant reservoir. Anywho, I am comfortable with everything I did except the timing belt. I had a hard time removing the crankshaft bolt and replacing the timing belt. I did turned the crankshaft CLOCKWISE and one time, the timing belt came off the crankshaft pulley (w/o me knowing) while turning COUNTERCLOCKWISE, but I kept turning the crankshaft hoping the camshaft would turn....maybe a couple of times or so. After putting the timing belt back on, I did turn it but with some resistance. But after that, I did set the TDC and marks according to the manual (1.5 engine lined up with the top of the engine block), turned the crankshaft COUNTERCLOCKWISE 3 teeth, loosened the adjusting bolt to tighten the timing belt, and tightening the adjusting bolt and torqued according to the manual. What did I do wrong and how can I get the engine to turn? Thanks guys n gals.
Should I go back and re-install the timing belt, being careful to follow exactly what the manuals says, plus the fact that this will be my 2nd time to do it?

sound like the resistance you are feeling are the valves hitting the pistons
if you cranked it over like that you might have bent some valves

I am going to be doing the timing belt, water pump etc. as well as my head gasket shortly in my 91 CRX.
With the head removed from the block would it be possible to align the #1 piston at TDC and separately rotate the camshaft gear so that the valves are in the corresponding position?
I ask because I am scared about going through with all the work and then bending my valves.

next time, after assembling everything, rotate the engine by hand 2x to make sure nothing hits. it seems as though you have a piston hitting a valve, and if you used the starter to find this out, there is a good chance the valve is already bent.
