Other Fuel System Fuel Injection System Problems of GMC Sierra 3500

While driving down a very busy street, the engine died. I lost all my power steering and brake. I was very lucky that I was not on a very busy highway. I had it towed to hedrick's Chevrolet in clovis CA. It took 2 days for them to check it out. They said when they went bring it in to the shop it started up and they could not find anything wrong with it. I picked the truck up and the next day it did the same thing again. I called the dealer and they told me to press the pump on the top of the filter housing until I could no longer press it. I did that and it started up. Be came very obvious that they were aware that the fuel filter housing was causing the injection system to lose suction I took it back to the dealer and they replaced the fuel filter housing. I have since found out that this failure is a common failure. Evidently there is an o ring in the housing and it fails and based on fact that their service person was able to tell me how to start the truck, they new of these failures and never told owners about this.

Injector failures on 2001 GMC duramax 6. 6 diesel engine. Injectors failed and replaced under warranty at 167,000 miles, failed again at 197,000 miles and replaced under warranty. G m customer service said they would replace them under warranty if they failed again in such a short period of time. Injectors failed at 234,000 miles and gm customer service renigged on their word. Many others have had failures in 30,000 to 40,000 miles. They are replacing parts with remanufactured parts and they are not lasting. Gm dealers are charging $3600. 00 to $4,500. 00 to replace these injectors out of warranty. It is plain that they know that there is a problem with the injectors when they extended the warranty on injectors from 100,000 to 200,000 miles or seven years. They get away with this because most people do not drive their vehicles that much in seven years. All I wanted was a fair deal and did not get it.
