If you are running the stock fuel pump on a blowthrough Nikki, you need to stop what your doing, take a deep breath, and thank God you haven't blown it up yet. You need to research what all associated upgrades you will need to successfuly run a blowthrough setup. You have missed about a dozen other thing you need for this to work.

Now this is the stock 12a pump (not S4), right? If you were boosting, no fuel was making it to the carb. The stock pump only puts out a couple psi. You need the base pressure (5 psi or whatever) + amount of boost + margin. With the proper regulator, you can run a FI pump for your setup. Let's hope you didn't blow it up.
Step 1: verify compression...
EDIT: Look at bad 83's mod list for an example of what you need for your setup.

Thanks Kent. I have sent him a PM to hopefully clear up his issues. I can't stress enough about how important it is to do ALL the research you can before undergoing such a project. It's easy to throw all the parts on there, not work, then blame the car. Properly tuned and setup, I can speak from personal experiance that a 12A blowthrough is a blast to drive.
