2004 5.7 92.000 miles..have sporadic issues where it won't start..crank but no fire...I unhook the battery and let it sit couple minutes and it starts right up.ive replaced the crank.map.and camshaft sensor..no codes still does the same thing...does anyone make a replacement harness?

 

Harness would make sense if you changed its position. Dropping power on/off and it works typically points at electronic issues like ecu. What makes you think its the harness?

 

the wires that go from the main harness to the crank position sensor and knock sensor are a tad crispy. Someone installed headers and i think the wires got hot...just trying to locating a good harness .and I'd rather not try and splice into the original.

 

probably best bet is good used
