After getting Injectors tested found all four had high leak back. reconditioned injectors fitted programmed in cleaned out rest of fuel system and new filter and car started and run perfect.
Went on road test with it and after about 6 miles glow plug light started to flash and went in to limp home. when I put the computer on up popped the same fault code again.
After sitting in the corner crying for a while I doubled check all my connections and tried re programming the injectors again and went on another road test and after two 20 plus miles run the car seems to be going fine.
Thanks for input from all some times you want to just hope that luck is on your side and you get away with the one unit. Should no better buy now.
