I just replaced the engine in my 1999 ford escort but will not start?

It sounds out of time but it is not
what is the problem

I'll bet it sounds out of time because it is out of time.

JJ. You are an idiot. I now nothing about engines, but even I can tell this. It turn out there are two timing marks in this engine. One on top, the other on the bottom cog. Both must be on the mark in order for this motor to run. I found that on YOU TUBE. How does it feel to realize you are nonsequitor.
