Gmc yukon xl 2002 getting no spark
We changed the fuel pump and the filter but
still no start. So we tested to see if we were
getting a spark and there was none. Where
do we go from here?
Check crank position sensor. See attached link to troubleshoot it, http://troubleshootmyvehicle.com/gm/4.8L-5.3L-6.0L/how-to-test-the- crank-sensor-1
