Default 5.3l wont start popping back through intake

So i just finished my 5.3l swap in my 1985 chevy K5 blazer. So when i finally got the nerve to turn the key it started to popping back throught the intake. So my put my scanner on it and it gave me a code for crankshaft sensor. So i replaced it with a new 1 and still did the same thing. Help anyone!!!!

Do a crank re-learn, and double check your wiring on the crank sensor, cam sensor, injectors, and coils.
