No fuel pressure

So my barn find car, 89 IROC 305 TBI w/ mouse eaten wiring, won't start, still. I installed a fuel pressure tester adapter inline with a new fuel filter, as I wanted to check fuel pressure. My pump runs, you can hear it, but the gauge shows no pressure. While cranking I can hear the injectors pulsing, but no fuel comes out. Any ideas? I thought maybe it was the little rubber hose in tank, but I can't check until Thursday. I was gonna cut an access hole for the pump, but can't figure out how I would get the pump out of the tank with those hard lines on it.

Anything helps

Thanks,
BA

Re: No fuel pressure

I got my 97's fuel pump out that way. It also had a hole in the flexible hose going from the pump to the hard line.
