I installed everything correctly, the chain lines up with the sprockets, but when I turn the chain by hand using the crank at the bottom of the engine, the chain moves a few links, then locks up, I can't turn it clockwise any more. I can turn it counter clockwise, just not clockwise. Any suggestions?
It appears that you do not have the timing correct on the camshaft/s and the crankshaft. The intake or exhaust valves are hitting the pistons when you turn the engine over. You need to make sure that the marks are exactly correct. NOW, for the big question,,,,,,, Was the chain broken? Was the engine running when it broke? I have seen this myself and repaired one, This will likely bend 2 exhaust and 2 intake valves. Good luck.

There are alignment marks on the timing set,and before you remove the old timing set,you must get cylinder number 1 in the firing order to Top Dead Center....then you can remove the old,and reinstall the new,timing set,but pay careful attention to the marks on each gear,in relationship to each other and where they line up.The new timing gear and chain set should have directions on where they are to line up,if not,you need to buy a Chilton manual for your specific car,as i don't have the specific information for your 3.1 engine.It sounds like your timing is WAY off,and when rotating the crank,a piston is hitting a valve...that means it's WAY out of phase...do not start the engine until resolved.The camshaft actuates the valves in relation to the crank and pistons' position,and when the valves open or close is VERY important for the engine to run properly,this is what i'm talking about (phased in) correctly.

chk all the tools you used, sometimes one will have just enough magnetism to steal small parts when you aren't looking. chk your solvent pan or in the pully you laid aside. a parts store would have one..

You have messed up the valve timing. I hope you haven't damaged the engine.
How, if everything lines up?
I have had customers swear that the job was done correctly, but low and behold it wasn't !! One thing is for sure you did something wrong when you put it back together, do you agree with this?
Obviously something isn't right, yes. My mechanic buddy set up the chain, I had to add the fixed and adjustable chain guides, and put the cover back on. When I turned the crank, the coloured chain links didn't line up, so I removed the tensioner and the intake sprocket and rotated the chain the 5 links or so until it lined up with the triangle on the exhaust sprocket, then replaced the intake sprocket, which naturally lined up with the diamond and coloured link accordingly. I didn't move anything mechanically in the engine, I merely took the chain off and rotated it a few links.
I gave up at 4am, gonna have another look in today's daylight. Thanks for your help so far, Dennis, I'm hoping I haven't damaged anything too! I didn't force anything, just turned until it physically stopped - the tension remained as it would be when operating normally.
As long as the starter wasn't used to turn the engine you will be fine. Do you have a service manual? If not google it, i think the whole repair procedure will come up with pictures. You can also download the manual from www.alldatadiy.com for a reasonable fee. You can buy a used factory manual set at faxon auto literature on line.
Thanks Dennis.
Nope, turned manually with a wrench. I have a Haynes manual, which basically tells me what I did and how to do it, it doesn't troubleshoot. There are only 5 pieces to this, 3 sprockets and 2 chain guides, how did I mess this up?!
