CONDITION:
Some vehicles may exhibit fuel pump noise whine and/or low fuel pressure, sluggish performance, loss of power or hesitation most evident during the
first five minutes of operation or under heavy acceleration. The condition may be intermittent and temporarily eased when the accelerator pedal is
temporarily released and then reapplied.

CAUSE:
The fuel pump may contain a tight bearing that causes internal binding in the pump.

CORRECTION:
