Owner Letter

October, 1996

Dear GM Customer:

As a valued customer, your complete satisfaction with your GM truck is our goal. In keeping with this goal, we want to let you know that we have discovered a problem that could affect your vehicle and we want to take care of it at no charge to you.

In certain 1996 S/T 4-door model vehicles, such as yours, some vehicles may have been shipped with the incorrect fuel pump assembled in the fuel sending unit. With the incorrect fuel pump, which has a lower flow rate, the vehicle would exhibit hard starts in cold start situations and hard starts with lack of power at launch in hot start situations. These hard starts could be as long as 10-13 seconds and give the customer the impression of a "no start" condition. Additionally, in hot start situations, the "Service Engine Soon" light may illuminate and codes be set in the VCM.

To be absolutely sure that your vehicle is to specifications, your GM dealer will perform a test to determine that the correct fuel pump is installed, and replace the fuel pump if it is not.

Instructions for performing this service have been sent to your GM dealer, and parts are available. Please contact your GM dealer to arrange a service date as soon as possible. This procedure will take approximately 15 minutes to test and 2 hours and 20 minutes to replace the fuel pump, if necessary, but you should ask how much additional time your dealer will need to schedule and process your vehicle.

The enclosed postage paid owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please furnish us the complete name and address of the person you sold or traded your vehicle to and return the card to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our product.
