I am a little confused. Did your son make the decision to give up the pacifier or did you? Either way, there just may have been too much change in too short a time for him.
Sleeping through the night requires relaxation and a feeling of safety--for children or adults. You may want to go back to the pacifier until he gets used to sleeping well in the bed. Keep another transitional item in the bed with him (the stuffed animal or special blanket, or whatever he connects with). Then, once his new situation has gelled, you can transition to no pacifier. Even if he initiated the no pacifier, he may need to go back to it.
Also, does he have a set bedtime routine? This can be really quick 10-15 minutes or longer, whatever works that signals to his body that it is time to get ready for bed.
My boy has his bath, lasts 15-20 minutes because he LOVES it, then a massage/rub down with lotion, get into pj's, brush teeth, and a story or 2 and quick song as he lays down. The key is that it is the same order every night. Even if we have a crazy night, he will get a 2-3 minute splash in the bath. This helps him get in the sleep frame of mind.
Good luck!
