*START AND STALL CONDITION

For a complete wiring diagram Refer to Section 8W.

Possible Causes

CURRENT PCM DTCS

CURRENT SKIM DTCS

THROTTLE POSITION SENSOR SWEEP

TP SENSOR NO.1 VOLTAGE GREATER THAN 0.92 VOLTS WITH THROTTLE CLOSED

ECT SENSOR

OTHER POSSIBLE CAUSES FOR START AND STALL CONDITION

FUEL CONTAMINATION

Diagnostic Test

1.CHECKING DTCS

Are any DTCs present?

Yes

Refer to the appropriate Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

Go To 2

2.CHECKING SKREEM DTCS

NOTE: If you are unable to communicate with the SKIM/SKREEM, refer to the VEHICLE THEFT AND SECURITY ELECTRICAL DIAGNOSTICS in Section 8 and perform the appropriate diagnostics.

Are there any SKIM DTCs?

Yes

Refer to the Sentry Key Vehicle Theft Security Electrical Diagnostics in Section 8.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

Go To 3

3.TP SENSOR SWEEP

Was the voltage change smooth?

Yes

Go To 4

Replace the Throttle Position Sensor on the manual throttle body or the Throttle Body Assembly on an ETC throttle body.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

4.TP SENSOR NO.1 VOLTAGE GREATER THAN 0.92 VOLTS WITH THROTTLE CLOSED

Is the voltage 0.92 or less with the Throttle closed?

Yes

Go To 5

Check for a binding throttle condition. If OK, replace the Throttle Position Sensor or the Throttle Body Assembly for ETC vehicles.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

5.ECT SENSOR OPERATION

NOTE: For this test to be valid, the thermostat must be operating correctly.

NOTE: This test works best if performed on a cold engine (cold soaked).

NOTE: If the vehicle was allowed to sit over night with no engine start, coolant temperature should be near ambient temperatures.

NOTE: If engine coolant temperature is above 82° C (180° F), allow the engine to cool until 65° C (150° F) is reached.

Did the Engine Temperature value increase smoothly and did it reach at least 82° C (180° F)?

Yes

Go To 6

Replace the Engine Coolant Temperature Sensor.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

6.OTHER POSSIBLE CAUSES OF START AND STALL CONDITION

Do any of the above conditions exist?

Yes

Repair as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

Go To 7

7.FUEL PUMP DELIVERY

Was the No Start condition solved after following the above diagnostic test?

Yes

Test Complete.

Check for contamination/water in the fuel. Ensure the fuel being used in this vehicle meets manufactures Fuel Requirement, refer to the service manual.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
