Bad fuel pump?
Turning the ignition on I do not hear the pump kick on. I tested for power on the tan wire with my multi meter, got nothing. I ran a hot wire directly from the battery to the "G" terminal on the ALDL, no pump. I then ran that hot wire directly to the tan wire at the bulkhead inside the car, no pump. Am I missing anything or is it time for a holley blue?
Here is a picture of the "tan" wire just to make sure I am sending juice to the right one.

Very interesting. If it turns out mine is junk I will definitely look into that pump.
You have one on your car?

Re: Bad fuel pump?
On top of the things mentioned above, I just checked the inline fuse on the inner fender and it was fine.
I am starting to think about the fuel pump relay, but I am not 100% sure I checked for power at the pump the right way. Looks like I can't get the pump to run off power from the car or by jumping power to it.
