Over the last few days, my XFire has been taking longer and longer to start. It cranks and cranks and cranks and I usually have to try to start it 2 or 3 times before it'll catch. It will start and drives OK at lower RPM but when I noticed that it bogs down a little bit above 3000 RPM.

I checked the codes and got a P0410 and P174 which indicates it's got an air leak and running lean. I checked under the hood and did find a vacuum line that came off so I reconnected it but the problem continued.

I also noticed that it's running +20-25% fuel trim and the computer pulled timing back 15-20 degrees.

If I turn the key on but don't start the car and do this 2 or 3 times, it starts up pretty quickly.

So, does this sound like a fuel pump going out if it takes a few tries to build up enough fuel pressure to start?
