Help! civic won't start

I recently replaced the engine in my '97 Civic EX and now it won't start. I get ignition, and the starter is working, but it doesn't start up. It gets about 2 rapid thuds and then stops. By thuds I mean the sound of ignition twice in a row. What are some things I could check ?

Well, before checking the engine, i would check into a VW or a german car. Japanese cars are good daily drivers and such, but with superior engineering and the option of diesel cars from VW, and speed along with reliability from BMW, and what not. if you would like a neat hatch back, the MK1 Rabbit, or MK2-5 GTI are awesome cars.

hit me up if you decide to go Euro/Better
