Does the 2007 Ford Focus have a timing belt or chain?

The 2007 Ford Focus came standard with a 2.0L 4Cylinder engine and there was also an upgrade option to a 2.3L 4Cylinder engine. These models will both make use of a timing chain that will likely not need to be replaced during the life of this vehicle. Starting in 2005 Ford switched the Focus over to using chains for all their engine types. The 2004 and older models will use a timing belt. Since You have a model with a timing chain it likely shouldn't need any repairs but if it does You will be looking at spending between $800 and $1300 for a full replacement.
