come on all you london boys theres enough of you living close to jon nit round and get it going for him. im sure it just needs somebody with good diagnostic skills and it should be back on the road. once you've driven the car again you'll forget all about selling it
have you tried taking all the plugs out, cleaning them,crank the engin over for a good 30 seconds,refit the plugs and then try to start it,remember when you do your battery must be fully charged they need a lot af power to kick it back to life.if you've got fuel,a spark it should fire.
try it it worked for me and my had'nt run for 7 years
good look sorry i can't help any more but i live in yorkshire
