There are two special splined sockets you can find on the Special Tools tab above used to remove the injectors and the delivery valves.
If the problem is the injector you can have it tested, cleaned and balanced; a new nozzle installed; or replaced with a new one.
If the problem is at the IP delivery valve you should have the IP bench tested. The valve itself should only be fiddled with professionally.
If its missing at start it could be the GP is out.....
