Kyle,
Don't forget to release the pressure in the fuel rail before taking anything
off of it. Just grab a rag and cover the area around the test port (tire valve
looking thingy on the fuel rail) and press the shrader valve down (just a bit)
to release the pressure. It won't make a big mess at all with a rag
there...and the rag will soak it all up. (Done that too many times already.)

> 3. Lift the fuel rail/injectors up off the engine/manifold
> 4. Remove the injectors from the fuel rail
> 5. Remove the wiring connectors from the injectors

> 7. Reinstall new injectors onto the fuel rail
> 8. Reconnect the wiring connectors onto the injectors
> 9. 'Bleed' the computer out; hold the key on for 15seconds
> 10.Reconnect the battery cables
> 11.Start it up and check for leaks
