Long Cranking With "DRY" Start

Symptoms:

Long cranking engine runs normally once started and no black exhaust smoke or heavy fuel smell occurs.

Generally, the cause of the dry start complaint is insufficient available voltage(s). This type of long cranking is not caused by a leaking injector.

Troubleshooting Hints:

- Battery properly charged (minimum 12.5V).
- Ignition coil terminal connections (tight), secondary high tension ignition wires (without leakage or corrosion).
- Spark plugs (type, condition, proper gap).
- DME Fault Memory (call up, print, and investigate accordingly).
- KL30/B+ Fusible Link(s) and all battery junction block connections must be in good condition without dynamic resistance.
- The negative battery cable should be checked for a tight metal to metal connection at both cable ends.
- The ground strap between the oil pan and the frame rail (engine ground) can suffer reduced electrical flow due to a loose connection or a painted contact area. The strap (if used) should be removed and the contact area cleaned as required.
- Central ground connections for the DME Control Unit must make good contact at the vehicle's ground point (see appropriate ETM for locations).
- All connectors at the main and fuel pump relay multiplugs must be tight and locked into place.
