Hi all, I'm new to the forum. I have a 2000 Outback wagon that I was keeping a year for my son (out of the Country) that I would start every couple of weeks. It ran well, until I parked in front of the house for a couple of weeks, then it wouldn't start. The gas cap wasn't messed with, so I don't think anyone put anything in the tank. It cranked OK, and the engine would catch for a few beats (like a second or two), then just stop. If I tried to start it again right away, it would crank but nothing fired unless I waited a minute. This annoyed me so much I put it up for the winter, and this spring nothing had changed. The battery was toast, so I replaced it and it cranks fine, engine catches a few beats, then stops. Here's what I checked so far- the pump comes on when the ignition is turned on. When cranked, It pumps fuel out of the fuel line post filter, so I don't think its the pump or filter. I pulled a plug, and it seems dry, even after being cranked for a while. I cranked it with the plug out, and there is no mist coming from the spark plug hole. The plug is clean, and it sparks fine when cranked. If I spray starter fluid into the throttle opening, it starts great, and will run as long as I give a shot every few seconds. So this sounds like a fuel problem. I'm thinking it might be the fuel pressure valve, but one of the two screws is in a really bad spot, and it looks like I'll have to take the whole rail off just to get the pressure regulator valve off. I could be the fuel pump, but as I said, its pumping gas when cranked. Could something be shutting the fuel pump off when the engine starts to fire up??? Can the pump work enough to move some gas into a cup, but not build up enough pressure to feed the injectors? (I'm from the days when fuel pumps worked on a lever riding on a cam on the crankshaft- that should date me) I'd replace the fuel pump, but that's a hundred bucks or more, and a lot more if replace the whole assembly- and I'm not even sure that's it. Perhaps after the first few cylinders fire the injectors stop opening up? Do they have fuses? Could that mean an ECM problem? I have an Actron scanner- no trouble codes. I don't know what the rest of the freeze frames mean. As I said, its been a while. I tried to siphon the old gas out of tank, but it sounds like cars have valves now to prevent that, I guess I missed that development. Any ideas? Thanks
