I have a 2001 Subaru Outback and can’t get it fully started. It stopped getting gas on the highway and now it won’t turn on. I’ve changed fuel pump, fuel filter, and fuel relay. It sputters but it doesn’t get a full stream of gas from the fuel line therefore won’t stay on and running. The alternator has been replaced, the air filter, the battery.... I don’t understand why my car can’t turn on and stay on. It’s trying!
