INTRODUCTION
BASICS
The following listed items should be checked prior to starting any troubleshooting:
Ensure engine serial number on the ECM matches the serial number on the cylinder block.
Walk around the vehicle. Look for obvious problems such as leaks (air or liquid).
Inspect the ECM for worn isolators, debris or bolts lodged between ECM and cylinder
block.
Ensure the fuel supply shut-off valve is set to
full on
.
Check that the fuel filter is secure and tight.
Check for a restricted air filter.
Inspect truck frontal area for air flow restriction through the CAC and radiator.
Ensure that the fuel tank level is correct and that the fuel tank is full.
Look for any vehicle damage.
Investigate any prior repairs, if applicable.
Check for broken wiring connectors.
Check for poor mating of the connector halves or terminals not fully seated in the
connector body (backed out terminals).
Look for improperly formed or damaged terminals. All connector terminals in the problem
circuit should be carefully inspected to determine proper contact tension. Use a mating
terminal to test the contact tension.
Check for electrical system interference caused by a defective relay, ECM driven solenoid,
or a switch causing an electrical surge. Look for problems with the charging system
(alternator, etc.). In certain cases, the problem can be made to occur when the faulty
component is operated as in the case of a relay.
Verify that alternator grounds are clean and making good contact. Disconnect the
alternator belt to test.
Wiggle wires and harnesses to try to make the problem active, or re-occur.
