My car is consuming more Diesel. I have replaced all 4 Injector nozzles and serviced the fuel,pump with a repair Kit. But still no improvement. What can I do next?
The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem. The
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related
problems. Also engine mechanical problems can and do cause many
drive-ability related problem such as rough idle and other symptoms.

Injectors could be blocked but i would go with an injector pump or fuel pump.

did you purge the air from the fuel system, or try to start it with ether? you may want to check the timing again if no fuel is being supplied to the engine.

Get a professionally rebuilt pump. Don't try to mess with rebuilding yours, it isn't worth it. I know the rebuilt pumps are high ($450) plus, but it will pay off in reliability and performance.
