Im new to this site and i dont know if im doing this right....Alright i got a 89 Z24 about 2weeks ago for about 700 bucks and the engine only had 128k on it and i wanted something with more power so i pulled the old 2.8 and swapped in a 1988 Grand Prix 2.8 liter with only 79k on it and changed over the intake and extras from my old 2.8 and just dropped the new motor in and now it wont start at all. Its turning over and makes spark but just wont start. Im not sure what it is...the fuel pump is working fine but it just wont start. I jumped it and it sounds like it just keeps dying. I dont know what else too do...need help!!!
