Cut out on me the other night , AA out etc. got it to garage today and they reckon the diesel pump is goosed and gave me a ballpark of a grand to sort it

I only paid a grand for it , granted it is a banger and has nearly 120k miles on the clock but its ran great for over 8 months with only one fault and has came in very handy , but I dont really fancy forking out that kind of cash on it .
Being pretty much clueless on technical side to cars , I wondered if anyone can share any knowledge on this fault and perhaps give an indication if the ballpark figure is correct?
Failing sorting the car any suggestions what to do with it ? will scrappys pay cash for it ?
This comes at the end of a week where I've flushed my phone down the toilet (gone, sewers) , broke down at traffic lights looking like a right twat and had problems at work ........bah humbug .
