Test 14: No Start

NO START CHART

TEST 14		NO START
STEP	INSPECTION		ACTION
1	CHECK PASSIVE ANTI-THEFT SYSTEM 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 anti-theft system. Is the system activated?	Yes	See ANTI-THEFT -- PASSIVE ANTI-THEFT SYSTEM (PATS .
1		No	Go to next step.
2	ATTEMPT TO CRANK ENGINE NOTE: Verify fuel pump shutoff switch is set (button pushed in). See INERTIA FUEL SHUTOFF (IFS) SWITCH . Does engine crank?	Yes	Go to 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 proper repair procedure. Does vehicle start now?	Yes	Vehicle is an intermittent No Start. See TEST 3: INTERMITTENT .
3		No	Go to next step.
4	CHECK FOR VREF AT THROTTLE POSITION (TP) SENSOR Disconnect TP sensor. Key ON, Engine OFF (KOEO). Measure voltage between VREF circuit (BR/W) and SIG RTN circuit (GY/R) at the TP sensor connector. Was voltage between 4.0 and 6.0 volts?	Yes	RECONNECT TP sensor. Go to 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 Pin 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 vehicle. RERUN PCM Quick Test. See PCM QUICK TEST .
5		No	Go to next step.
6	CHECK PIP IN THE PCM NOTE: The WDS 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 15: IGNITION SCOPE TEST to check ignition coils, plugs and wires. If OK, go to next step.
6		No	See CRANKSHAFT POSITION (CKP) SENSOR MALFUNCTION .
7	CHECK FUEL PRESSURE WARNING: Before servicing 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 . Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE . Install fuel pressure gauge SST 49 UN01 010. Key ON, Engine OFF (KOEO). Using WDS 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 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 one minute after turning off fuel pump. Does fuel pressure remain within 16 kPa (5 psi)?	Yes	RESTORE vehicle. Go to next step.
8		No	See TEST 4: FUEL DELIVERY SYSTEM .
9	CHECK FUEL INJECTORS FOR VPWR NOTE: Check at least two fuel injectors, one on each bank. A no start condition can exist only if greater than 50% of the fuel injectors are without VPWR. Disconnect any two 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 next step.
9		No	REPAIR VPWR circuit.
10	CHECK FUEL INJECTORS' ABILITY TO DELIVERY FUEL Connect Fuel Pressure Gauge SST 49 UN01 010 to Schrader valve. Locate and disconnect the fuel pump shutoff switch. Cycle key several times. Monitor SST while cranking the engine for at least five 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 .
10		No	REPLACE PCM. See POWERTRAIN CONTROL MODULE (PCM) .
