I replaced the head gasket I aligned the timing marks on the cams, and the crank. when I run the vehicle there is no power and will not rev over 2500 rpm's. Is it possible that the crank is out of alingnment? the pulley marks when I turn the motor manually is showing about about 20 degrees before tdc
The crank or the cam may have warped due to overheating or wear, you may need to go back and recheck torque of everything taken apart
You cannot set the timing anymore , the engine computer does that now , have you checked to see if the camshaft position sensor was re-positioned properly .
the exhaust valve camshaft may not be positioned properly.
there are holes in the camshaft pulleys and the cylinder head that must be aligned and retained with bolts before you remove the timing belt / chain
SOURCE: timing chain guide broke..jumped time and broke middle gear.
remove the #1 sparkplug place a long screwdriver in the sparkplug hole point touching the top of the piston turn the crankshaft around until the screwdriver is almost pushed out (top dead center)
check to see that the distributor rotor is pointing at the #1 sparkplug wire it must be; if not: turn the crankshaft again until it does
then turn the camshaft around until both valves above the #1 piston cylinder are closed
this is correct; now find the marks on the belt camshaft sprocket gear and, crankshaft gear aline the belt marks with the gear marks and, install the belt

SOURCE: Replaced timing belt but now the car wont start
timing these new motors today are difficult, your timing may still be off. You'll need to get a timing gun. Also did you make sure that the motor was Top Dead Center(TDC).
SOURCE: top end cam and crank chains are off!
I can help you with this.You have to start all over again.There should be three chains all together. Two short ones and one long one.The two short ones are for the cams. We are going to start with those two first.The 90 degrees they are talking about the timing mark on the gears on the cams should be 90 degrees from the flat surface of the cylinder head.The easiest way to do is find the marks on the gears and then find the links on the chains that are different color line those up with the timing marks on the gears. There should be 12 links one color link to the other. Set those and put the tensioners on little tricky on those. When you are going to set the big chain the cams are going to move some don't worry about as long as those color links stay on the timing marks. They will move a little and it looks like they are off but they are not. Once you do that the long chain also has different color links also align those with the timing marks on the cam sprokets and crank gear.Install your tensioner for the long chain. You have to collapse the tensioner all the way in and install collapse. Once in with a screw driver pry in against the tensioner to realease it. If you fail to do this you will hear chain hitting the metal cover when you start it. Once you have this together you can turn the engine in the direction that it normally runs manually and it shouldbe free. Keep in mind that once you turn the engine you will never get those timing marks to align the way they were it still ok. Hopefully this will help. I have built a lot of these engines for my customers.

INFO:99 Dodge Stratus-
I've had crank sensor malfunction twice in as few as 4 months. This time I determined that the frayed belt, abused sensor, perhaps it was frayed first time around and missed it I don't know? Maybe this helps the next guy.
