GMC C4500 owners have reported 1 problem related to other fuel system fuel injection system (under the other fuel system category). The most recently reported issues are listed below.
Vehicle has complete fuel system failure. In talking to dsu in portland, they told me that this is a common problem in this year of vehicle and that a check valve in the fuel pump disintegrates and destroys the entire fuel system. They told me that gm knows about this issue, has changed the check valve in newer injection pumps but will not warranty and or recall these pumps. This causes a $12,000 repair.
