need some help
 

hey guys I need some help with my car. I replaced the clutch and the front seal since it was leaking. now my car wont start, it was running before. I have a new opti in it its getting spark. if I take out the #1 spark plug it starts but I put it back in and nothing. so any info you guys might have I would really appreciate it.
its a 95 Z28 lt4 hot cam setup pace setter long tubes magna flow exhaust lt4 knock sensor.

Does it crank with #1 plug in??? If it cranks it possible that some plug wires may be crossed.
