Question '93 Impreza: No Start, fuel pump?

Trying to get a potential rallycross project off the ground. 1993 Impreza FWD, manual. Been sitting for a while, replaced battery and terminals. Car gets spark and everything else works, cranks like no problem.

Removed the fuel line to the filter, no pressure but fuel was up in there. Cranking, no fuel movement, no noise from the fuel pump. Fuel Pump Relay clicks strongly, 12V at the connector and when switched/energized. Back at the fuel pump connector, I am only seeing 4 or 5 volts.

I really don't want to throw parts at it, as a FPR is $30 and a new pump is $85. The last option is to straight-wire 12V to the pump and make sure it runs I guess.

PS-- added 2 gallons of fuel as well, gauge works and level raised. When I get the fuel pump running, I will try to empty the old fuel out of the lines and replace the filter after running it for a bit to clear the crud.

Thoughts? Thanks!

Last option-- I see that my parts store shows a Fuel Pump Inertia Cutoff Switch for the car. Where might that be located?

Just a thought---sounds like a bad wire more than a bad pump. As far as the inertial cutoff---has the car been hit hard at any point?
