Now i removed return pipe of fuel and there was no sign of fuel while cranking. I think the pump electric circuit is OK but mechanically it z not working.If there is problem with injectors or voltage of injectors then fuel should come from return pipe. code 2111 is false when engine is not running. Audi repair manual guides how to check the fuel pump and uses a remote control at fuse 17.what is an alternate way of checking the pump without removing it?
