ENGINE DOES NOT START / UNDER NO CIRCUMSTANCES

2.0 16V JTD, 2.2 16V JTD

The engine does not start. When the key is turned the instruments light up as normal, the starter motor turns, but the engine does not start up.

STEP	OPERATIONS TO BE CARRIED OUT	TEST RESULTS
0	PRELIMINARY CHECKS	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check: that the inertia switch has not been operated; presence of fuel in the tank; air intake circuit; correct operation of the flow modification valve; correct operation of the exhaust manifolds. that there are no leaks or seepage from the high and low pressure fuel pipes	Move on to Step	1. Intertia switch operated	1. Restore correct operation
			2. Lack of fuel	2. Add fuel to the tank
			3. Air filter dirty or partly blocked	3. Replace the filter element Op. 1048A14 AIR CLEANER FILTERING ELEMENT - REPLACE.
			4. Flow modulation valve working incorrectly	Move on to Step
			5. Exhaust blocked	5. Restore exhaust manifolds to working order
			6. Presence of leaks	6. Eliminate leaks
1	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the Examiner diagnostic equipment to the diagnostic socket.Check: that there are no errors in the control unit (the Code system in particular) Carry out active diagnosis of flow modification valve	Move on to Step	1. Error detected in the control unit	1. Continue following the instructions for the diagnostic equipment
		Move on to Step	2. Solenoid valve not working	2. Check the continuity of the wiring < R1 >, if necessary, replace the solenoid valve < R2 > See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
2	FLOW MODIFICATION VALVE ACTUATOR CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check operation of the pneumatic actuator	Move on to Step	Actuator not working	Replace electro-pneumatically controlled throttle casing
3	HIGH PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	With the diagnostic equipment connected to the diagnostic socket, check that the diesel pressure parameter is correct following the instructions in test 1060D	Move on to Step	Pressure not correct	Move on to Step
4	INJECTOR HIGH PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check, as described in procedure 1060C, that the leaks of diesel from the injector recirculation connections are only slight and about the same as one another.	Move on to Step	Persistent leak from one injector	Replace the injector
5	LOW RETURN PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check, as described in test 1060A, that the pressure in the return pipe to the tank is less than 1 bar	Move on to Step	Pressure above the maximum limit: return pipe to the tank obstructed	Repair the pipe, if necessary, replace it
6	LOW SUPPLY PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check, as described in test 1060B, that the diesel pressure between the filter and the pressure pump is between 2 and 3 bar	Move on to Step	Pressure below the minimum limit or above the maximum limit Pressure below the minimum limit or above the maximum limit	Move on to Step
7	LOW SUPPLY PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Constrict the return pipe, downstream of the valve, and carry out test 1060B again with the pipe constricted checking that the pressure at the filter outlet stays below 2 bar	Move on to Step	Pressure rises to 5 bar: pressure regulator valve on filter mounting incorrectly adjusted	Replace the valve
8	LOW SUPPLY PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check that the difference in pressure upstream and downstream of the filter is less than 1 bar	Move on to Step	Difference in pressure more than 1 bar	Replace the fuel filter cartridge Op. 1044B20 FUEL FILTER FILTERING ELEMENT - REPLACE
9	CHECK LOW SUPPLY PRESSURE	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check that the supply pump pressure at the filter inlet is more than 2.2 bar	Move on to Step	Pressure below 2.2 bar	Move on to Step
10	LOW SUPPLY PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Measure the difference in pressure between the electric pump outlet and the filter inlet and check that it is less than 0.3 bar	Move on to Step	Difference in pressure more than 0.3 bar	Replace the pipe
11	LOW SUPPLY PRESSURE CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check, as decribed in test 1040AA, that the pump supply voltage is equal to 12V and that the current absorption is between 2 and 10 Ampere	Move on to Step	1. Voltage < 12 volt	1. Check electrical wiring See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT
			2. Current > 10 Amps: pump defective	2. Replace the fuel pump assembly Op. 1040A70 SUBMERGED PUMP ASSEMBLY COMPLETE WITH LEVEL GUAGE CONTROL - R + R
			3. Current < 2 Amps: pump obstructed	3. Replace the fuel pump assembly < R1 > and clean the fuel tank Op. 1040A70 SUBMERGED PUMP ASSEMBLY COMPLETE WITH LEVEL GUAGE CONTROL - R + R
12	CHECK ON CORRECT OPERATION	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Replace the high pressure regulator and check that the fault is no longer present.		Fault persists	Move on to Step
13	CHECK ON CORRECT OPERATION	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Replace the pressure pump and check that the fault is no longer present		Fault persists	Contact the Service Department for further information on the problem
14	CHECK ON CORRECT OPERATION	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Replace the engine management control unit and check that the fault is no longer present		Fault persists	Contact the Service Department for further information on the problem
