91 4.0 cranks, has spark and fuel but won't start
 
Originally I wasn't getting spark so I changed the cap and rotor, seems to be getting spark but won't start, could it be the cps? I checked it and it seems to be ok but I'm not sure what it could be at this point... Thanks in advance

Is this problem new? did you do anything prior to the problem like change the distributor or wires?

I just got it and the original engine had problems, when I took it apart there was gouges on the cylinder walls in the 1 and 5 cylinders.. I got a new engine an put it in and originally the 1 and 5 cylinders were not sparking.. I used the new block and head from the new engine everything else from the old, I am not sure what is causing the same cylinders not to spark tho... I changed the cap and rotor and the it didn't help, could I have a bad distributor? The spark is intermittent, I'm getting it on and off so I'm not really sure
