CRANKS NORMALLY BUT WILL NOT START
DESCRIPTION
•  Starter cranks the engine at normal speed but the engine will not run.
•  Refer to the symptom troubleshooting “No.7 Engine stalls” if this symptom appears after engine stalls.
•  Fuel is in the fuel tank.
•  Battery is in normal condition.
POSSIBLE CAUSE
•  Poor fuel quality
•  Intake-air system restriction
•  Fuel line restriction
•  EGR system malfunction
•  Glow system malfunction
•  Fuel warmer malfunction
•  Fuel pressure sensor or related circuit malfunction
•  Suction control valve malfunction (built-in supply pump)
•  Fuel pressure limiter malfunction (built-in common rail)
•  Fuel leakage
•  Fuel filter clogging
•  Incorrect fuel injection timing
•  Erratic signal from CKP sensor
•  Erratic signal from CMP sensor
•  V-reference supply circuit malfunction
•  ECT sensor or related circuit malfunction
•  Supply pump malfunction
•  Fuel injector malfunction
•  Low engine compression
•  Improper valve timing
•  Main relay malfunction
Warning
The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before performing the fuel system services:
•  Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.
•  Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injury or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete “BEFORE REPAIR PROCEDURE” and “AFTER REPAIR PROCEDURE” described in this manual.

Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION
1
Inspect the following:
•  Fuel quality (e.g.: include water contamination, winter/summer blend)
•  Fuel line/fuel filter clogging
•  Intake-air system restriction
Are all items normal?
Yes
Go to the next step.
No
Service if necessary.
Repeat Step 1.
2
Note
•  Ignore DTC P0122:00, P0123:00, P0222:00 or P0223:00 while performing this test.
Disconnect the Accelerator pedal position (APP) sensor connector.
Measure the voltage at the APP sensor connector VREF terminal (terminal D and A) and ground with ignition switch ON.
Specification
4.5—5.5 V
Is voltage normal?
Yes
Go to the next step.
No
Inspect PCM terminal 2S and 2T and the related circuits.
3
Connect the M-MDS to the DLC-2.
Switch the ignition to ON.
Retrieve any DTCs.
Are any DTCs displayed?
Yes
DTC is displayed:
Go to the appropriate DTC test.
(See DTC TABLE [MZR-CD 2.2].)
Communication error message is displayed:
Inspect the following:
•  Open circuit between main relay and PCM terminal 2C or 2F
•  Open circuit main relay and PCM terminal 2I
•  Main relay stuck open
•  Open or poor ground circuit (PCM terminal 2B, 2E, 2A or 2D)
•  Poor connection to vehicle body ground
No
No DTC is displayed:
Go to the next step.
4
Inspect the glow system operation.
(See ENGINE CONTROL SYSTEM OPERATION INSPECTION [MZR-CD 2.2].)
Is the glow system operation normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning part according to glow system operation results.
5
Inspect for fuel leakage from the fuel pipe.
Is any fuel leakage found on the fuel pipe?
Yes
Repair or replace if necessary.
No
Go to the next step.
6
Visually inspect the CKP sensor and the teeth of the pulse wheel.
(See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [MZR-CD 2.2].)
Are the CKP sensor and the teeth of the pulse wheel normal?
Yes
Go to the next step.
No
Replace malfunctioning parts.
7
Visually inspect the CMP sensor and the teeth of the pulse wheel.
(See CAMSHAFT POSITION (CMP) SENSOR INSPECTION [MZR-CD 2.2].)
Are the CMP sensor and the teeth of the pulse wheel normal?
Yes
Inspect the following PIDs:
(See PCM INSPECTION [MZR-CD 2.2].)
•  ECT
•  RPM
If the PID value is not as specified, repair or replace the malfunctioning parts.
If the PID value is normal, go to the next step.
No
Replace the malfunctioning parts.
8
Inspect the fuel pressure sensor.
(See FUEL PRESSURE SENSOR INSPECTION [MZR-CD 2.2].)
Is the fuel pressure normal?
Yes
Go to the next step.
No
Replace the common rail.
(See COMMON RAIL REMOVAL/INSTALLATION [MZR-CD 2.2].)
9
Inspect the suction control valve.
(See SUCTION CONTROL VALVE INSPECTION [MZR-CD 2.2].)
Is suction control valve normal?
Yes
Go to the next step.
No
Replace the supply pump.
(See SUPPLY PUMP REMOVAL/INSTALLATION [MZR-CD 2.2].)
10
Is the engine compression correct?
(See COMPRESSION INSPECTION [MZR-CD 2.2].)
Yes
Go to the next step.
No
Inspect the following:
•  Damaged valve seat
•  Worn valve stem and valve guide
•  Worn or stuck piston ring
•  Worn piston, piston ring or cylinder
•  Improper valve timing
Service if necessary.
11
Inspect the fuel injector.
(See FUEL INJECTOR INSPECTION [MZR-CD 2.2].)
Is the fuel injector normal?
Yes
Go to the next step.
No
Repair or replace if necessary.
(See FUEL INJECTOR REMOVAL/INSTALLATION [MZR-CD 2.2].)
12
Inspect the fuel warmer.
(See FUEL WARMER INSPECTION [MZR-CD 2.2].)
Is the fuel warmer normal?
Yes
Go to the next step.
No
Replace the fuel warmer.
(See FUEL FILTER DISASSEMBLY/ASSEMBLY [MZR-CD 2.2].)
13
Inspect the EGR system operation.
(See ENGINE CONTROL SYSTEM OPERATION INSPECTION [MZR-CD 2.2].)
Is the EGR system operation normal?
Yes
Remove and inspect the supply pump and the common rail.
(See SUPPLY PUMP REMOVAL/INSTALLATION [MZR-CD 2.2].)
(See COMMON RAIL REMOVAL/INSTALLATION [MZR-CD 2.2].)
No
Repair or replace the malfunctioning part according to EGR system operation results.
14
Verify test results.
•  If normal, return to the diagnostic index to service any additional symptoms.
•  If the malfunction remains, inspect the related Service Information and perform repair or diagnosis.
―  If the vehicle is repaired, troubleshooting completed.
―  If the vehicle is not repaired or additional diagnostic information is not available, reprogram the PCM if later calibration is available. Retest.
