  1. Test the engine coolant temperature (ECT) sensor. Compare the ECT sensor value to the intake air temperature (IAT) sensor value on a cold engine. The ECT and IAT sensor values should be within ± 3°C (5°F). If the ECT sensor is out of range with the IAT sensor, test the resistance of the ECT sensor. Refer to «Temperature Versus Resistance»(ref-318492-S30177931502009061700000) for resistance specifications. Replace the ECT sensor if the resistance is not within specification. Refer to «Engine Coolant Temperature Sensor Replacement (ECT 1)»(ref-318492-S13297815602009061700000) or «Engine Coolant Temperature Sensor Replacement (ECT 2)»(ref-318492-S06072816692009061700000) . If the sensor is within the specification, test the ECT circuits for a high resistance.
  2. Test the fuel pump relay operation. The fuel pump should turn ON for 2 seconds when the ignition is turned ON. Refer to «Fuel Pump Electrical Circuit Diagnosis»(ref-318492-S23589188632009061700000) .
