you dont need to get another motor unless you want to or need to. First off 3 things make a car start, compression, spark, and fuel. Check them each and make sure there are all there. First Spark..I dont know if this is a ghetto backyard mechanic way but its how I do it... take one of the spark plug hoses out of the head, take a screwdriver (with plastic handle) and stick it insdie the spark plug hose (make sure it touches the metal ring inside) and then hold the hose over something metal ( a bolt will do just fine) and have someone try and start the car..if it sparks you got spark. ( I hoped I explained it good..if you have any questions email me). Second if there is no spark check fuel...on the firewall you will have a fuel filter...loosen the bolt the fuel comes out of (not too much !) and have someone turn the key as if they were going to start the car..if you got fuel it will leak a lil out or spray a lil (depending on how loose you lossened it). Thrid is compression...the easiest way to check this is go to sear or pep boys or auto zone and buy one and just follow the directions. Hope this helps good luck
