No you need a wire from the stock nova fuse block near your steering column from the IGN power source (12V cranking)

You have several issues though with what you are trying to do. Right now nothing is firing your fuel pump!!!

I have the fuel pump wired differently....I have the magnafuel pump with dual relay harness wired into the ign terminal into the stock nova fuse block in the floor board. The fuel pump is working correctly. Let me see if i can move it and swap the ign terminal in the floor board to the computer

Edit: I read it wrong on what you said about the fuel pump my bad...you are correct nothing is firing the fuel

Theres a terminal labeled ign from the stock nova use block that i had powering my fuel pump...i removed it and put it on C100 A9 and nothing. I put my volt meter to the wire that is coming from my nova fuse block and there is power.

On the first picture you can barely see an "N" next to gauges it is the IGN terminal. 2nd picture you can see I did a female spade connected to it (yellow wire feeding into the black).

DId you review the LT1swap website for information on how to do this? You really are going about this backwards by not re working your harness before trying to fire it off. The harness re work instructions are on the LT1 swap web site.

Yes i did read over the how to on lt1swap, but i wanted to keep my harness stock and not have to mess with all the rewiring. I will look at the site again and see if there is something i missed. I appreciate your help!
