The first ones are injectors, the fact all 4 are affected says electrical fault like wiring, control module etc. Check the fuses.

The 01312 one looks like data bus: http://wiki.ross-tech.com/wiki/index.php/01312 

Last one is airbag.

Could be a main power relay. They generate the same problems and fault codes. Yeah, could be a fuse.

Fault to ground could mean that the injectors are actually ok, as is the wiring, but the 12v supply isn't there. So the ECU thinks that the supply has been shorted out (to ground). It should say, short to ground or faulty supply...

Like most fault codes,  always suggest clearing them first, see what returns. Your airbag fault for example is basically a false positive.
