Test Description

The numbers below refer to step numbers in diagnostic procedures.

1. 3
   
   It is necessary to disconnect 24x crank sensor in order to ensure that 7x signal is read in 3x reference parameter.
2. 4
   
   Spark Tester (J 26792) presents a more difficult load on secondary ignition than a normal spark plug. If a miss or a hesitation is caused by a spark plug that is not firing, spark tester should also not fire.
3. 5
   
   Use a 5 percent saltwater solution in a spray container to induce voltage arcing to ground through faulty insulation of spark plug wires.
4. 7
   
   If no spark condition follows suspected coil, that coil is faulty. Otherwise, ignition module is cause of no spark. This test can also be performed by substituting a known good coil for one causing no spark condition.
