7 Reset the ECU: Use the diagnostic scanner to reset the engine control unit (ECU) to clear any stored trouble
codes and reset the ignition timing parameters.
8 Adjust the timing (if necessary): Using a diagnostic scanner or manufacturer-specific tools, adjust the
ignition timing to the specified value.

9 Reassemble: Put the distributor cap and rotor back in place and secure them properly.
10 Reconnect the battery: follow step 11 from the mechanically controlled distributor type procedure.
11 Start the engine: Follow steps 12-15 from the mechanically controlled distributor type procedure.
These steps should help ensure proper service of both types of distributor, keeping the vehicle’s ignition system
in good condition.

Distributor type pump
Distributor pumps are also known as rotary pumps. This distributor pump has a single pumping element to supply
fuel to all the cylinders. A single inlet rotor is used to supply fuel to each injector. But for delivery, as many outlets
are given as many ejectors and as many pipe lines are connected to Papa. So that all the injectors are supplied
with the same amount of diesel at regular intervals. The piping element has two cylindrical plungers against each
other. It has a straight hole connected to a horizontal hole. This horizontal bore is provided with as many delivery
ports as the number of cylinders, all the parts are fitted in an aluminum housing with a governor, this pump is
currently used on most diesel engines.

Servicing and over-oiling
After dismantling the FIP all the parts should be first flushed with diesel and then cleaned with pressurized air.
Camshaft nose wear should be checked with dial test indicator. End play, side play should be checked and
necessary changes should be made. Check working clearance between plunger and barrel. Check the wear of
