Description
This table assumes that the battery condition and the engine cranking speed are OK. If not, refer to Engine for diagnosis. Also, make sure that there is adequate fuel in the tank.

Diagnostic Aids

Notice: Refer to J 35616-A Connector Test Adapter Kit Notice in Service Precautions.

^ Use the J 35616-A Connector Test Adapter kit for any test that requires probing the ECM harness connector or a component harness connector.
^ Unless the engine enters the Clear Flood at the first indication of a flooding condition, a no start may result.
^ If the steps above do not correct the symptoms, refer to Symptoms and Hard Start for diagnosis. Symptom Related Diagnostic Procedures

Test Description
The numbers below refer to step numbers on the diagnostic table.
3. The ground wire to the body is located below the rear of the battery. The ECM ground is located on the mounting bracket the ECM attaches to. All grounds should be tight and free of any corrosion.
4. Some Powertrain DTCs may require the engine to crank over for up to 15 seconds before setting. Powertrain DTCs that may prevent the engine from starting include the following:
^ Input sensors such as CKP, ECT, MAF, APP or TP
^ Control circuits such as fuel pump relay or fuel injectors
^ Internal control module DTCs for the ECM or the TAC Module
^ Powertrain theft deterrent DTCs
5. Make sure the theft deterrent system is functioning properly before continuing with this table. A Theft Deterrent System fault may cause a no start or start and stall condition.
6. Compare the values with the normal values found in the engine scan tool data list. Sensor values that have shifted may prevent the engine from starting.
