NOTESThere must be no present or stored faults.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III
or MODUS.
IF THE RELAY DOES NOT CLICK 10 TIMES
Check the condition of the fuel pump relay connector (see NEW TWINGO or E33, component code 236).
Check the condition of the engine management computer connector (component code 120).
Check the condition of the Protection and Switching Unit connector (CLIO III or MODUS, component code 1337).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise change the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●3AC between components 120 and 236 (for NEW TWINGO or E33),
●3AC between components 120 and 1337 (for CLIO III or MODUS).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, there is a fault in the Protection and Switching Unit (the fuel pump relay is in the Protection
and Switching Unit and is not removable) (for CLIO III or MODUS).
Perform fault finding on the UCH (see 87B, Passenger compartment connection unit) (for NEW TWINGO or
E33) or the Protection and Switching Unit (see 87G, Engine compartment connection unit) (for CLIO III
or MODUS).
If the fault is still present, contact the Techline.

IF THE PUMP DOES NOT OPERATE
Check the condition of the fuel pump connector (component code 833).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
With the ignition on, check for + 12 V on connection 3N on the fuel pump, component code 833.
Run command AC015:
If there is no + 12 V:
–disconnect the battery,
–disconnect the connector in the Protection and Switching Unit (for CLIO III or MODUS),
–Check the condition of the Protection and Switching Unit (see Wiring Diagrams Technical Note, CLIO III or
MODUS, component code 1337).
–Check the condition and connections of the UCH (see 87B, Passenger compartment connection unit)
(for NEW TWINGO or E33).
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the universal bornier to check the insulation and continuity of the following connections:
●3N between components 833 and 236 (for NEW TWINGO or E33),
●3N between components 833 and 1337 (for CLIO III or MODUS).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.

For CLIO III or MODUS:
Reconnect the Protection and Switching Unit connector and reconnect the battery.
If there is still no + 12 V on the fuel pump relay connector, there is a fault in the Protection and Switching Unit.
Carry out fault finding on the Protection and Switching Unit (see 87G, Engine compartment connection unit).
If the fault is still present, contact the Techline.
For NEW TWINGO or E33:
Reconnect the battery.
With the ignition on, if the + 12 V is still not present on the fuel pump relay connector, there is a fault in the engine
fuse and relay box.
Carry out fault finding on the engine fuse and relay box to check the 30A fuse and the continuity of the following
connection:
●BP17 between components 120 and 397, 238 and 397.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
IF THE PUMP DOES NOT OPERATE
Check that there is an earth on connection MF on the fuel pump, component code 833.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the fuel pump.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
Repeat the conformity check from the start.

WARNING
During this operation, it is essential to:
–refrain from smoking or bringing incandescent objects close to the work area,
–protect yourself against fuel splashes due to residual pressure in the pipes,
–wear safety goggles with side guards,
–wear leaktight gloves (Nitrile type).
IMPORTANT
–To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
–To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Remove 1 l of fuel at the fuel filter outlet, in the engine compartment (see MR 385 (Modus), MR 392 (Clio III),
MR 411 (New Twingo), or MR 442 (E33), Mechanical, 19C, Tank, Fuel tank: Draining), using a pneumatic
transfer pump (part no. 634-200) and place it in 1300 ml plastic cup (part no. 77 11 171 413).
Close the plastic cup with its cover (part no. 77 11 171 416) and let the fuel rest for approximately 2 minutes.
This type of plastic cup is used to prepare paint.
Is the fuel cloudy or does it
separate into two parts?Water is present in the petrol; the fuel is not correct.
Drain the fuel circuit, including the tank (see MR 385 (Modus),
MR 392 (Clio III), MR 411 (New Twingo), or MR 442 (E33),
Mechanical, 19C Tank, Fuel tank: Draining).
Visually compare the fuel removed with the correct petrol.
