Test 10: No Start

NO START REFERENCE CHART

TEST 1		NO START
STEP	INSPECTION		ACTION
1	CHECK PASSIVE ANTI-THEFT SYSTEM (PATS) NOTE: This vehicle might have an anti-theft system, which may be activated, causing the no start condition. Verify by viewing anti-theft indicator on instrument panel or a DTC P1260 may be present. Verify if vehicle has an anti-theft system. Is the system activated?	Yes	See PASSIVE ANTI-THEFT SYSTEM (PATS) .
1		No	GO to the next step.
2	ATTEMPT TO CRANK ENGINE NOTE: Verify fuel pump shutoff switch is set (button pushed in). See INERTIA FUEL SHUTOFF (IFS) SWITCH REMOVAL/INSTALLATION . Does engine crank?	Yes	GO to the next step.
2		No	See STARTING CONCERNS .
3	IDENTIFY TYPE OF NO START NOTE: The purpose of this test step is to identify intermittent no starts in order to guide the technician to the correct repair procedure. Does vehicle start now?	Yes	Vehicle is an intermittent no start. See TEST 3: INTERMITTENT .
3		No	GO to the next step.
4	CHECK THE REFERENCE VOLTAGE TO SIGRTN/ETCRTN NOTE: DTCs P0642 and P0643 are set due to VREF circuit concerns only. When diagnosing DTC P0642 or P0643, follow the path for VREF concerns. Key OFF. Disconnect suspect sensor. Key ON, engine OFF (KOEO). For ETCREF concerns. Measure the voltage between: (+) Suspect Sensor Connector ETCREF, Harness Side and (-) Suspect Sensor Connector ETCRTN, Harness Side For VREF concerns. Measure the voltage between: (+) Suspect Sensor Connector VREF, Harness Side and (-) Suspect Sensor Connector SIGRTN, Harness Side Is the voltage between 4.5 - 5.5 V?	Yes	GO to the next step.
4		No	See TEST 1: VEHICLE REFERENCE VOLTAGE (VREF) .
5	CHECK FEPS CIRCUIT FOR SHORT TO POWER Key ON, engine OFF (KOEO). Measure voltage between 13 (V) at data link connector D-01 and battery negative post. Key OFF. Was voltage greater than 9.0 volts?	Yes	REPAIR short to power. RESTORE the vehicle. REPEAT the PCM Quick Test. See PCM QUICK TEST .
5		No	GO to the next step.
6	CHECK PIP IN THE PCM NOTE: The IDS or equivalent tester must be connected to a reliable power source that is powered with the key in the START position (such as directly to the vehicle battery). Also, verify that the vehicle battery is fully charged. Access PIP PID. While viewing the PIP PID, crank engine. Is the PIP PID switching on and off?	Yes	Key OFF. See TEST 11: IGNITION SCOPE TEST to check ignition coils, plugs and wires. If OK, GO to the next step.
6		No	See CRANKSHAFT POSITION (CKP) SENSOR MALFUNCTION .
7	CHECK FUEL PRESSURE Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . WARNING: Before repairing or replacing any components in the fuel system, reduce the possibility of injury or fire following warning, caution, and handling directions found in general test 5 (fuel delivery). See TEST 4: FUEL DELIVERY SYSTEM . Install fuel pressure gauge SST 49 UN01010. Key ON, engine OFF (KOEO). Using IDS or equivalent tester, Select Diagnostic Data Link. Access the fuel pump Active Command Press START to run fuel pump. Was fuel pressure between 380-482 kPa (55-70 psi)?	Yes	GO to the next step.
7		No	See TEST 4: FUEL DELIVERY SYSTEM .
8	CHECK FUEL PRESSURE LEAKDOWN Verify fuel pressure remains within 16 kPa (5 psi) of the maximum pressure for 1 minute after turning off fuel pump. Does fuel pressure remain within 16 kPa (5 psi)?	Yes	RESTORE the vehicle. GO to the next step.
8		No	See TEST 4: FUEL DELIVERY SYSTEM .
9	CHECK FUEL INJECTORS FOR VPWR NOTE: Check at least 2 fuel injectors, 1 on each bank. A no start condition can exist only if greater than 50% of the fuel injectors are without VPWR. Disconnect any 2 fuel injectors. Key ON, engine OFF (KOEO). Measure VPWR circuit (R) voltage at fuel injector harness connector. Is voltage greater than 10.5 volts?	Yes	Key OFF. GO to the next step.
9		No	REPAIR VPWR circuit.
10	CHECK FUEL INJECTORS ABILITY TO DELIVER FUEL Connect fuel pressure gauge. Locate and disconnect the fuel pump shutoff switch. Cycle key several times. Monitor SST while cranking the engine for at least 5 seconds. Is there a pressure drop greater than 34 kPa (5 psi) while cranking the engine?	Yes	The fuel system is not the cause of the no start. RETURN to DIAGNOSTIC INDEX 01-01A-383.
10		No	INSTALL a new PCM. See POWERTRAIN CONTROL MODULE (PCM) REMOVAL/INSTALLATION - 2.5L or POWERTRAIN CONTROL MODULE (PCM) REMOVAL/INSTALLATION - 3.0L .
