Default Wouldn't start, now runs but has gas smell from exhaust

1998 Legacy Outback, 2.5l. I washed it yesterday, pulled it into the driveway, everything was fine. This morning, it wouldn't start - cranked over, didn't even seem like it was trying to catch, strong gas smell. Tried various times over the morning, still nothing. Checked spark at one terminal on the coil, it was fine.

Tried again this afternoon and eventually it caught and started to run. Turned it off, started up again right away. Waited an hour, tried it again, starts up right away.

However, there's a strong gas smell from the exhaust and a faint white/grey smoke that's only visible if you're looking closely. I haven't run it long enough to see if that goes away as it warms up. Also, when tapping the throttle, it bogs down for half a second and drops a few RPM before kicking up.

Any guesses? I think I'm going to take it in to get looked at tomorrow anyway.

if it was flooded, its going to take awhile for all that fuel to clear up, take it out and beat on it a bit, should clear it right up.

You were right about the flooding, the gas smell and slight exhaust smell went away after taking it out for 15 minutes to warm up. It's running great, tons of pull at WOT, nothing seems unusual once it warmed up.

Here's the three things I did messing around with it, none of which makes much sense in terms of fixing it to me:

1) Pulled a wire at the coil end and checked it for spark. There was spark, still didn't start.
2) Floored it while starting it - it didn't start that time, but when I came back to it 20 minutes later, it did after turning over a few extra times.
3) Turned it on, moved the AT shifter through Park->Drive and back. This is when it started, but I did this right after #2, so it's hard to tell which may have affected it.

Is there a sensor that might not have come on properly when it was in Park the first time? I would think there'd be one to stop it from cranking maybe, but not cause it to fail to start.

Maybe an injector was clogged and cleared when I tried to start it with it floored? I did run injector cleaner through it last tank.

well it sounds like it was flooded, The right thing to do was no. 2, flooring it will shut off the injectors.

It was probalby coincidence that it started after no. 3

now the question is, how did it get flooded?

bad fuel pressure regulator, fuel injector getting stuck open.

Might want to dump a bottle of fuel system cleaner in it, and maybe change the fuel filter.
