Always worth rechecking. I've had the gauge on dozens of times, and if not secured properly will show no or low fuel pressure, but then it's usually coming out the adapter.
You could have fuel coming out the lines at the filter, but not enough pressure to get it to the rail.
If no or low pressure (should be around 60 at the rail like @exp500 said), then replace the pump. Get an ACDelco GFV pump. It's a slight upgrade over the GFU pump. Got mine at 1A Auto for a good price, and make sure to shop around. Some places overcharge.
In the how to replace fuel pump it says to get a pump as you have but you are saying get the GFV. Which is correct?
