Hey I bought my first Honda 91 accord a buddy and I did a complete engine swap due to cracked block. After installation I get a code 4 thrown up when I check the engine light, I looked online and found out it may be bad distributer I was wondering if it may just be the timing being off due to be distributer being put on. Any thoughts?

 

ECU doesn't know what the ignition timing is set to.
Code 4 is crank position sensor, on the 90-95s it is inside the distributor.
