Question about Subaru Cars & Trucks
How do i test the fuel pump
I assume that you have fuel injection. Some cars allow you to put a pressure gauge on the fuel rail. If it takes you three times to start your car and you have over 100 thousand miles then you can pretty much say your pump is shot. Many times about 500 miles after a fuel filter change the pump will go out. A poor mans way would be to disconnect the fuel line and hold a finger over the line to see how much pressure is there. This is very dangerous because you could wind up with gas in your eyes or the car on fire. Fuel pressure requirements vary from car to car. Example, the Jeep Cherokee uses pretty high pressure and will not run unless the pressure is high.
