ISSUE:

NO start, hard start, rough idle and lack of power may be caused by a camshaft distributor drive gear that is out of specification. This can cause early camshaft or distributor gear failure at less that 10,000 miles.

ACTION:

Install a new camshaft assembly and distributor assembly that are within specification. Refer to the following procedure for service details.

SERVICE PROCEDURE

1. Check the camshaft and distributor gear for signs of wear or failure.

2. Replace both the camshaft assembly and distributor assembly if either gear is badly worn or has failed. Refer to the appropriate Light Truck Shop Manual, Section 21-23 for removal and installation procedures.

CAUTION:
DO NOT REPLACE JUST THE DISTRIBUTOR GEAR.

3. Install a new service camshaft assembly (D9TZ-6250-A) for 6.1L and 7.0L engines and (C8SZ-6250-A) for 7.5L engines.

4. Replace the distributor assembly (-12127-) in all cases. Refer to the Dealer Master Parts Catalog to determine the correct distributor assembly.
