edc light
 

hi i have a sprinter van 2001 313 cdi ive just changed the fuel pipes that go to the fuel pump on the front of the engine situated above the fan pulley now when i drive it above 20 mile an hour edc light comes on and engine cuts out so i turn off ignition then on restart and if i keep revs under 2000 it drives ok it ticks over great
can you advise please
