KA24E to KA24E swap, with some problems

[Jornez]

Well guys, and gals, I just did my first swap and im done, or well i thought i was, I got everything in and im assuming everything in right but im have some troubles with getting it cranked, it will turn over and turn over but wont crank, Its getting fuel and spark, due to the fireballs bouncing out of my header occasionally, Does anyone know what could be the problem or what i can do to get it cranked? i dont know if many people has had this problem but i cant seem to get it right, Im so eager to get it running and being back in my s13, Its was a 89 and im swapping a single cam right back into it, Ive tested the plugs and wires so i know they're sparking and i know its getting fuel because when i went to check the injectors i forgot to depressurize it and it spewed in my face, What could have gone wrong?
