5 HARD START AND NO START DIAGNOSTICS 143

Description

WARNING: To avoid serious personal injury,
possible death, or damage to the engine or
vehicle, make sure the transmission is in neutral,
parking brake is set, and wheels are blocked
before doing diagnostic or service procedures on
engine or vehicle.
The Diagnostic Form (Hard Start and No Start side)
directs technicians to systematically troubleshoot a
hard start or no start condition and avoid unnecessary
repairs.
This section shows detailed instructions of the tests
on the form. The manual should be used with the form
and referenced for supplemental test information. Use
the form as a worksheet to record all test results.
Do all tests in sequence, unless otherwise stated.
Doing a test out of sequence can cause incorrect
results. If a problem was found and corrected, it is
not necessary to complete the remaining tests.
See appendices for Diagnostic Trouble Codes (DTCs)
and engine specifications.
