Audi4kq fuel pump

[Roger Mounsey]

 According to Bentley, if the amperage exceeds 8.5 amps, replace fuel
pump. Note, tho, the work sequence - the battery must be fully charged
and then oxygen sensor heating element disconnected beforehand, 
 As for the fuel injectors, it might be too late, but you could at least
try some Red Line max strength fuel injector cleaner ( said to clean
injectors  within a tankful of gas).
