hey all, just after some advise, was driving my gu3 zd30 the other day and engine warning light came on, and lost power, im guessing limp mode. took it to a diesel specialist and had it scanned, it is coming up with code 77. he has told me that my pump is stuffed and i need to buy a new one. i have tried to do a little research on the code before forking out for a new pump but cant seem to find much on code 77, except some references to 0707. are they the same code? or does anyone now what code 77 is exactly? would like to make sure it is the fuel pump before getting it reconditioned. when i first got the code a mechanic mentioned that it may be a blocked fuel filter, so had that replaced and fault still appears. when i first start the car it doesn't show code and seems to have full power for about 5 seconds, then engine light appears and power loss. cheers, Geoff
