Please help.

OK I have a 91 LS that I have been doing a OBD2A JDM B18C Type R swap in. I have the motor in all of the wires wired in have followed all of the guides that i have found online but I still cant get it to turn over. I have changed the Main Relay since I noticed a few dry joints, I have changed the ignition coil for a MSD Blaster 3 along with a MSD cap and rotor. Cleaned the grounds, I am getting fuel but I will only get 1 spark when I go to crank it. I really have no idea what is going on or what I need to do to get this thing running again. could anyone Please help me?

USE APPROPRIATE SUBJECTS
Your subject should be a broad description of what your problem/question/topic is. For example, don’t post a thread with just “HELP” or “QUICK QUESTION” in the subject. Doing this will be regarded as pure laziness and the thread will be promptly deleted. Using appropriate subjects helps the search engine function better!. Also, do NOT use a different subject than what your thread is about, just to get attention. It will also be deleted.
