Narrative:

I started my engine on the ramp at ZZZ taking my student to an instrument checkride. The AWOS was inoperative but it was VFR conditions with fog present south of runway xx extending to about 2;000 feet. Down the runway. Runway XX1 was clear of fog so I chose to taxi from the ramp to runway XX1 for departure.I made a radio call on the CTAF stating I was at the ramp taxing to XX1. I visually scanned the area and began to taxi. There was nobody else making radio calls on the CTAF at this time. In order to get to runway XX1 I needed to cross runway XX2/xx. I taxied up to the XX2/xx hold short line; held short and made another radio call stating I was crossing runway XX2/xx. I looked both ways. Runway XX2 was clear and the runway xx end was foggy. With no objection from any other traffic I began taxiing across. While about halfway across the runway I saw a landing light and nav lights appear to my right coming on us quickly. I immediately went full power and vacated the runway.a cessna citation had begun it's take off roll on runway xx in the fog as I was crossing the runway on the clear side. He came blasting out of the fog at rotation speed and I just got off the runway in time to avoid a collision. The pilot of the citation then said; 'where were your radio calls?' to seemingly put the blame on me. I replied 'I've made all my position reports I didn't hear you say a word.' I think they were on the clearance frequency picking up and IFR clearance and didn't monitor CTAF. They began their take off roll without reporting it assuming the runway was clear.this was an extremely frightening experience that could have easily been avoided with proper nontowered airport radio communications. I personally think that it should be a requirement to monitor CTAF while picking up an IFR clearance or changing frequencies for any reason at a nontowered airport. And I think that there should be more strict take off minimums under part 91.
