as above rebuilt my mk3 xr3i after 2 years and she wont start, will fire but cuts out after 1-2 seconds.decent spark fuel at top of metering head and cold start valve will fire a little longer on easy start maybe 3-4 secs so def a fuel issue.is there a start point for setting these injections up i know they can be very sensitive but have already tried a little adjustment either way and nothing .any help with this issue would be great,cheers matty
