2012 Yukon SLE hard start issue
I am new here and have a 2012 Yukon SLE with the 5.3 engine. Had to replace the original fuel pump due to a rusted out top. Pump was replaced with a NAPA pump in June this year. Several weeks later it developed a hard start. The engine cranks as normal but doesn't come to life until you turn off...- PEI Yukon
