My GMC Yukon’s original fuel pump lasted for 14 years, 171000 miles, It was replaced July 5, 1013, it expired August 10, 2013, it again expired September 11, 2013.
The wiring has been checked, the new module wiring plug that is included with the pumps was properly installed, the new pumps just stop, DEAD.
Voltage is fine, When the new pump is installed it starts right up, HELP!!
I should add I have owned this Yukon since new, it has always been serviced, I have always changed fuel filters twice yearly, spring and fall, in the case of the failed pumps, the filter were always changed with the pumps, and the again 30 days later. The fuel has always been clean, I have always used branded fuels, Mobil. Exxon, Irving, Shell, Sunoco, only, Never ever off brand fuels.
