Sure it is possible. That is why it is important to replace the fuel filter every 36,000 miles. A dirty fuel filter will cause the fuel pump to work harder and cause it to fail prematurely.
Yes, that is possible. Change the filter and fluid and see if that solves the problem.
Yes, it is possible.
It is possible. Replace the filter and see if the symptoms disappear.
That could cause a change from solid to liquid, or from liquid to gas.

Possible lack of fuel pressure. Change your fuel filter first. Possible weak fuel pump.
Possible and so can a partially clogged fuel filter.

It can put a poisonous liquid in your body system and cause possible death, but if you wear sun screen your fine!
Possible cause of war?
Anything is possible but it is unlikely - the error code P1166 is for the primary oxygen sensor.
