It's been a very cold day here in Kansas City and my wife called to say that our 2003 4.4 X5 is on a neighborhood street NOT RUNNING. There is a heavy fuel smell inside and I see liquid on the ground directly below the engine which I'm pretty sure it is fuel. I've read some threads that mention a leaky fuel injector.

Does anyone have any direction and pictures of how to remove / replace a fuel injector? Any other ideas?
