after sitting all day or overnight, hard starting (about 2-3 seconds cranking). symptom like no fuel, but tried a test which presumably would indicate fuel regulator, but passed. Test was to turn on key, wait 10 seconds, then repeat 3 times. This had no affect, still was hard starting. next recommendation was to measure fuel pressure at fuel rail, but not obvious how to do this on the 2006. have a 2001 and this is easy to see test point.
thanks for any suggestions
