8 | CRANKS NORMALLY BUT WILL NOT START
--- | ---
DESCRIPTION | • Starter cranks engine at normal speed but engine will not run. • Refer to symptom troubleshooting “No.5 Engine stalls” if this symptom appears after engine stall. • Fuel is in 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 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 • Immobilizer system (PATS) and/or circuit malfunction (if equipped) • Low engine compression • Improper valve timing • PCM control repay 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.

No | Repair or replace wiring harness.
7 | Turn the engine switch to the ON position. Access the B+ PID. Is the B+ PID normal? Specification Battery voltage | Yes | Go to the next step.
No | Repair or replace wiring harness.
8 | Disconnect the coil connector. Turn the engine switch to the ON position. Is there battery voltage at coil connector terminal D (harness-side)? | Yes | Go to the next step.
No | Repair or replace wiring harness between coil connector terminal D and fuse panel.
9 | Inspect the following wiring harnesses and connectors. For advanced keyless entry is not equipped: • Between PCM terminal 89 and coil terminal A • Between PCM terminal 112 and coil terminal B For advanced keyless entry system equipped: • Between keyless CM terminal 3Y and coil terminal A • Between keyless CM terminal 3AA and coil terminal B • Between keyless CM terminal 4Z and PCM 87 • Between keyless CM terminal 4AA and PCM 95 Is there any malfunction (open or short circuit, terminal corrosion, etc.)? | Yes | Repair or replace malfunctioning part.
No | Go to the next step.
10 | 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 10.
11 | Note • Ignore DTC P0122, P0123, P0222 or P0223 while performing this test. Disconnect the APP sensor connector. Measure the voltage at APP sensor connector VREF terminal (terminal D and A) with the engine switch to the ON position. Specification 4.5—5.5 V Is the voltage normal? | Yes | Go to the next step.
No | Inspect the open or short circuit for wiring harness. • Between PCM terminal 82 and APP sensor terminal A • Between PCM terminal 63 and APP sensor terminal D
12 | Connect the WDS or equivalent to the DLC-2. Turn the engine switch to the ON position. Retrieve the any DTCs. Are any DTC displayed? | Yes | DTC is displayed: Go to the appropriate DTC test. Communication error message is displayed: Inspect the following: • Open circuit between PCM control relay and PCM terminal 119 or 120 • Open circuit PCM control relay and PCM terminal 105 • PCM control relay stuck open • Open or poor ground circuit (PCM terminal 1, 2, 3, 114 or 117) • Poor connection vehicle body ground
No | No DTC is displayed: Go to the next step.
13 | Inspect the glow system operation. (See RELAY INSPECTION.) Is the glow system operation normal? | Yes | Go to the next step.
No | Repair or replace malfunctioning part according to glow system operation results.
14 | Inspect the fuel leakage from fuel pipe. Is any fuel leakage found on fuel pipe? | Yes | Repair or replace as necessary.
No | Go to the next step.
15 | Visually inspect the CKP sensor and teeth of the pulse wheel. Are CKP sensor and teeth of pulse wheel normal? | Yes | Go to the next step.
No | Replace malfunctioning parts.
16 | Measure the gap between CKP sensor and teeth of the pulse wheel. Specification 1.5—2.5 mm {0.059—0.098 in} Is the gap within specification? | Yes | Go to the next step.
No | Adjust the CKP sensor position.
17 | Visually inspect the CMP sensor and teeth of the pulse wheel. Are the CMP sensor and teeth of the pulse wheel normal? | Yes | Inspect the following PIDs: (See PCM INSPECTION [MZR-CD (RF Turbo)].) • ECT • RPM If the PID value is not as specified, repair or replace malfunctioning parts. If the PID value is normal, go to the next step.
