Question about 1996 Subaru Impreza
Replaced fuel pressure valve. Fuel pressure is 28 psi at idle. 40 psi with vacuum hose disconnected. Car starts runs for 6 seconds then goes into a stall. Fuel pressure does not decrease when this happens. If I put vice grips on the return fuel line the fuel pressure goes up to 80 psi and the car runs forever. Very confused.
Check the volume of fuel! You may want to change your fuel filter!
When was the last your fuel filter ws changed?

Sounds like you need to replace your fuel pressure regulator.

If this had the problem before you worked on it then it could be bad gas. If after the fuel filter change, check the flow direction on the fuel filter and you may want to take off the filter and blow into it to see if it is clogged. Usually the fuel is looping around the system. Try taking off the fuel cap and start the car. It may be an air pocket and with the cap off it may eliminate the air pocket.
