Can a fuel filter be the cause of my car not starting?

What is your question?

Alright so I bought my car bout 8 months ago and it started giving me a trouble a month ago. It started out were it would crank up then go off maybe a few seconds later I would crank it back up and it would be fine. later I would come to find if my car was on half or more it would not do this only less than half a tank. so about two weeks ago my car was doing the same thing but this time it wouldn't come on after the second crank. so I tried to get jumped but it was not the problem. well so we put about 2 gallons of gas in it and put foot on gas pedal and it stayed on. I then put gas treatment and a thing to clean out the lines. and it worked fine till yesterday we tried all the same things but nothing is working and it was the same exact thing it was dong as two weeks ago.
