The timing mark on the crankshaft sprocket should be at the 12 O'clock position.....the timing mark on the intermediate sprocket should be at the 6 O'clock position...in other words, the two timing marks are aligned.
The drive pins on the 4 camshafts must be vertical or perpendicular to the cylinder head, ie 90 degrees to the cylinder head surface.

disconnect the battery is one way to disable the computer ,as for the timing marks i havent a clue what you are trying to do from the description you have given ,sorry

First make sure timing marks on crank and timing gear are pointing towards each other and in alignment. Next make sure that the camshaft gear pins are pointing down and at 90 degrees to heads. Put chains back on. Thats it. Make sure all the marks are exactly like I wrote or you will be tearing the motor back apart and doing it again.

will it start after cooling off? if so , check for fuel lines near anything that can get hot..(vapor lock) insulate or move them..
