Chart A-3 - Part 2 Of 3:

Injector and Ignition Control:

TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.

1. This test will determine if CKT 467 is shorted to ground.

2. This test will determine if CKT 467 is shorted to B+.

3. Each individual injector resistance should be 12.2 + .4 ohms at 20°C (68°F). Resistance will increase as temperature increases. An injector that does not meet specifications could cause the injector driver in the ECM to close and this would cause a cranks but no start situation.
