If you're not hearing a compression stroke, sounds like cam timing is way off. I would think if the chain broke you would hear a couple of compression strokes due to the valves being closed all the time on at least a couple of cylinders.
You didn't just assemble this engine, did you? I knew a guy that just assembled the timing chain and cams with no regard to timing marks and had the same thing happen.

I am still thinking a problem with your UDP's...
it may also now freewheel due to fuel washing down the rings. this can lower the compression enough to make it sound like this.
first your going to need to figure out why it's not starting.. if you have spark and fuel presure then pull out the plugs and clean them well and if the oil smells like gas then change the oil and try again.

I'm confused... Are you saying that when the key is turned you only hear it "clicking". Is the motor actually turning over? (if it's not, thats why you aren't hearing any compression)
Maybe I'm way off but i'm thinking it could be a dying battery or bad starter?
OK I was talking about the fuel pump clicking on and the engine spinning no huffing the timing chains are tight not loose at all I took the valve covers off I dont know how it could have Jumped time or even if it did but when I was driving it and gave it some gas it bogged out and started doing this...I just went and checked and its getting plenty of fuel it squirted to the top of my hood as far as spark how do i check that?

When you had the valve covers off, did you crank the engine and were the cams spinning? Any backfires when attempting to start it? I'm sticking with cam timing. If you have the covers off, bring it around to top dead center on number one cylinder and both valves should be closed. If they're not, somehow you jumped time. I've never had the chain covers off my engine. Is there a keyway on the crank pulleys that could have broke?
I dont know what you mean by keyway please explain if you are talking about that little slot i'm guessing its not broke I dont have the belt on and its turning the crank by itself but no huffing and the cams did move and it lightly backfired where the Hpipe is not out the tailpipes
yeah check your crank trigger wheel and crankshaft position sensor.. check to see if you have spark and then if you do remove the plugs and clean them well, this will also give a flooded engine time to dry out, then change the oil and try again.

nope still isnt fixed yet...timing is correct i have no spark and i have compression andeverything is in excellent condition as fars as internals go so i have no clue...can anyone help me figure this out
you have no spark?
Do you have underdrive pulleys on the car, if so then check the crank pulley and triggerwheel

svttech yeah i have UDP's and the crank pulley and trigger wheel is fine. I have pulled the timing chain cover and the valve covers off to check everything and everything is fine I just cant figure this out..
