any CEL codes?

Kiroshu

did you put it back together right.... sounds like maybe when you did that you may have forgotten or messed up the intake manifold gaskets..... if they are leaking it does this.... all lines hooked up.... wires in right places.....? Check engine light? If so get codes....

You DO have the VAFM back in place & plugged in, RIGHT?

Losing the knock sensor will throw a code, but I don't think it will prevent you from starting.

As TNRabbit hints: you need to take a deep breath and think systematically. Fuel, air, spark: what are you missing?

what is the VAFM and where is it located? Gaskets should be good only go on one way?

guntee1

can you get codes if it has not ran for more than a few seconds?

RMA

Can you take some pictures of the engine compartment and post them here.
Maybe 3 or 4 from diffrent angles.
Maybe we might be able to see something wrong, just maybe.
