A very late reply. Apologies to those who may have suffered the same issue in the mean time. After changing relays and pump we still had no power at the pump. I used the same jumper wire to drive the car to a local Subaru specialist. The problem was a corroded connector under the back seat. A connector I had no idea existed. The fix was cheap, diagnosis was expensive. The car still runs fine more than 3 years later.

Thank you. That will be the next step when I get back to the car.

Update: The used fuel pump and plug are installed. Now there is no power on the blue/yellow wire to the fuel pump, the ground seems good. As a temporary measure I ran a wire from the battery to the fuel pump wire. the pump runs and the car starts. I drove it this way about 10 miles (daughter's moving day). Any ideas what to check for no power to the fuel pump? The fuel pump relay is new. The fuses are good. I'm running out of ideas. Thanks!

Back from the bone yard. DMM says the pulled pump reads 3.3 ohm at the wires on the other side of the plug. It also reads 3.3 ohm at the pump connection. Total cost was $15.94 - $2 to get into the yard, $13 for the part, and tax. I tried the pump via jumper cables (to get further away from my car just in case there was a spark) and it ran for the brief second I applied power. Did not want to run it dry and overheat it. We'll see if this fixes the car of if I'm wrong about the root cause here. Sadly it will be days or a week until I get back to my daughters to install it.

Yes, I had the range on the DMM set too high. Heading to the U-Pull yard to get (hopefully) a used unit and car side plug (they usually toss that in for free). Only $9 for the part so not a big investment.

Thanks for the quick replies. I did check the ground, and the DMM read 0 ohms from the ground pin for the pump and the body (bare metal of a speaker frame). I found it problematic to check the voltages when the plug was connected to the fuel pump. I will double check the connector inside the fuel tank again, but I read 0 ohms across the two fuel pump pins. The one thing I did nto check was that there was 12v at the pump connector. The replacement fuel pump uses a two pin spade plug, not like the stock Subaru part. There is a '95 Impreza in a local u-pull boneyard. If the fuel pump is still there I think that will be what we try next.

First, thanks in advance for any assistance with this fuel pump problem. Short problem description - I have power to the fuel pump plug briefly at key on and when the engine is cranking. The pump does not run. The pump and the fuel pump relay have been replaced. The new fuel pump is a turbine unit from Napa. The is continuity from the connector through the pump motor, reads near a dead short. Do does the old fuel pump. The only thing I can think of that would be a problem is the electrical connector at the tank (fuel pump and sending unit. I found a small brass near the plug just before I took the pump back out ofthe tank again, so I suspect the plug may (car side, not the tank side) be the problem. With the pump out of the tank I confirmed that the fuel lines were completely dry when O popped them off and that the pump was not running at key on or while the car was cranking. It seems odd that the old pump (220K miles) and the new pump both would not work. Are there any other ideas? Is there any possibility there is 12v at the plug, enough to read on a DMM but not enough to run the pump motor? Thanks!
