Test Description

The number below refers to the step number in the diagnostic test.

1. 2)
   
   If the engine starts, the problem could be intermittent. Basic engine mechanical problems, the Vehicle Theft Deterrent (VTD) system (if equipped), and poor connections could cause a no-start condition.
2. 3)
   
   This step will determine if the cause of the no start or start and stall is related to the VTD.
3. 4)
   
   If the signal is over 2.5 volts, the engine may be in the clear flood mode which will cause starting problems.
4. 5)
   
   If the engine coolant sensor is below -22°F (-30°C), the PCM provides fuel for this extremely cold temperature which will severely flood the engine.
5. 6)
   
   Voltage at the spark plug is checked using the spark plug tester tool. No spark indicates a basic ignition problem.
6. 7)
   
   This test will determine if there is fuel pressure at the fuel injection unit and holding steady.
7. 8)
   
   Use the injector test light in order to test the injector circuits. A blinking lamp indicates that the PCM is controlling the injector.
