One problem related to other fuel system pump has been reported for the 2001 GMC Safari. The most recently reported issues are listed below.
The fuel pump on my GMC 2001 Safari van makes a loud whining noise. I am looking into why this would occur on a 4 year old vehicle. I have owned other GMC's and not heard of any such problems. I feel this to be a safety hazard and am looking to have it replaced by the dealer without charge as soon as possible.
