My fuel pump isn't working. I am putting a lt1 in a 67 cutlass. I am using the fuse box from the cars stock wiring harness. I have done a lot of reading up on what to do. I have wired a relay going to the fuel pump from the computer. I have power on that side but none on the side going to the pump. I also need to wire up a relay for my ignition also. I am stumped on that one too. I am going bone stock no add ons. Thanks for any help

I ran straight power to the fuel pump and it came on. So I know the pump works now. Just want to know if I have it hooked up right. I have 30 going to the pcm power and 85 ground 86 going to the point feed and 87 going to the pump for power

I am using a b body gas tank with a lt1 swap in a 67 cutlass. I don't know if it is suppose to be open or not. Honestly I didn't know there was a difference. I am trying to see how would I wire the ignition switch also.

From the diagram on shoebox's site it looks as though the relay is wired normally closed. Meaning the relay gate is closed and current will not flow unless 12v is applied. Make sure yours is wired correctly is my guess. If you are using the LT1 PCM then you also need VATS to be tuned out.
