Paul, i have have just checked this code for you the P0204 is a code for Cyl4 the - 008 part relates to a wiring fault between the ecu and the injector, so i would carefully check the wiring loom, these are troublesome at times

if you drive the Vehicle does it cut out when you are pulling up hill for instance

you could try swapping 2 injectors to see if the fault moves

P.S. if you give me a chassis no i can check the pin outs for you
