Rebuilt engine dies

So, I just finished putting my engine back together. Here's what I've replaced:

Pistons
Piston Rings
Rod bearings
main bearings
thrust bearings
head gasket
valves
timing belt
tensioner pully
vvt solenoid
starter motor
fuel filter

Last night after I finally got it back together and tried to start it up. It runs for maybe 3 seconds with loud random squeaking and then just dies. It almost sounds like the piston rings get stuck or something. I know the timing was all lined up before I started it up. Any suggestions of possible issues? Thanks

    The squeaking may or may not be related to the engine stopping, but it is something that needs investigated first before the stalling. If you have an assistant attempt to start the engine, can you hear approximately where the noise is coming from? (front or rear of engine, left side or right side, high or low?)

    Have you built engines before? What kind of pre-lube did you use, and where all did you put it? Was the engine turning over easily by hand? Does it still turn over easily by hand?

    As far as the engine stopping, that should be treated like any engine stalling condition, test and prove what you are losing. Spark? Fuel? Both? Neither?
