Fuel pump relay
I have been hotrodding my vette quite a bit lately so when I need to jet the Carb (Best and most cost effective replacement for the cross fire) I unplug the relay and run it out of fuel. I had it running the other day and decided to remove the carb so I unplugged the relay and fuel pressue did not drop??? I had to remove the fuse?? Is this right??? or with the computer removed and all the wireing changes have I created some gremlins??

If you installed a fuel pressure regulator before the carb... which you should have to reduce pressure (assuming the fuel pump is original) then your pressure should not drop. If I'm wrong here...I hope someone corrects me.
