need to be more specific with the details like what the engine, how long you had the car not running without an engine and such are. But since I dont know the specific I'll just give you the three basics to look for. Fuel= check you fuel pump and see if it turns on when you turn the key (you can hear it if you take off the carpet. Or it could be your fuel filter clogged and make sure you got the return line and feed correctly placed. Electricty= since its cranking your chances of having the starter and alternator be the problem are slim. make sure you got good ground contacts and if possible use a dielectrical grease. Oxygen= make sure the maf is placed correctly in how long away it is from the turbo (assuming you have a turbo). I know Ca engines have to be at least 12-15 inches away. Thats all I can think of with the very little info you give.
