not that i know of, and have ordered coil pack now so may have to do more trial and error finding

Why, the code is giving you the info. As said, make sure you`re getting power to the injector

have just been and had another look and have pluged code reader in again and it gave the same fault but for no 3 inj so i erased this and then started car and no fault light so im now thinking that this is going to be the coil pack would i poss be right with it doing that now??

If you've bought the new coil pack fit it and see, i along with a lot of the othere four pot owners have had similar problems. I changed the cam sensor and the car was fine for a good 20K or so and the coil pack started to fail on me at around 90K i replaced it with a known good second hand one.

Touch wood it's been all good since then, however i never had any codes about injectors stored :-/ :-/

ECU is reporting injector electrical faults so that is where I would be looking. It does not need a camshaft signal to validate the state of each injector driver so the fault code is likely to be correct.

Check the connectors are pushed onto the injectors properly and that the locking clips are there (not some lazy bugger left them off previously) Look carefully at both wires to each injector, has one snapped?
Check the earth wires that attach to the fuel rail, are any broken, loose or corroded.
Follow the injector loom back, looking for any connectors, i think the 4 pot goes direct from the injector to the big engine loom connector by the battery so should be OK but I have seen broken / corroded wire on the V6s big injector plug & socket.
If the fault code has moved from #4 to #3 that suggests a bad earth or loose connector.
