The following diagnostic steps will help prevent overlooking a simple problem. Also begin here to diagnosis a no-start condition.
The first step in diagnosing any driveability problem is to verify the customer's complaint by test driving vehicle under the conditions the problem reportedly occurred.
Before entering self-diagnostics, perform a careful and complete visual inspection. Most engine control problems result from mechanical breakdowns, poor electrical connections or damaged/misrouted vacuum hoses. Before condemning the computerized system, perform each test listed in this article.
NOTE:
Perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure.
