I just changed my fuel filter, now my car won't start. It just cranks and cranks, until finally the battery went dead. Fuel isThere was nothing wrong with the fuel pump until I changed the filter, so I am assuming I need to prime the line somehow. Is there anyhing I need to do? Can anyone offer any suggestions?

First there is no need to prime the line the fuel pump has enough pressure. When you change the fuel filter it will start and die the crank for a few and start that is all there is to changing the fuel filter. Now are you sure there is fuel with enough pressure at the injector rail? Do you have spark at the plugs? This may sound redundent but I believe go back to the basics and go from there. Let me know what find and we will go from there.

I'm not sure if it has any pressure or not. How can I check it? I tried starting the car for over an hour, and finally the battery went dead. Before I have someone come to jump start it, I need to figure out how to fix it, or we're just wasting our time. I took off the new filter, and a little gas drain out, but not much. I just gave it a tune-up, so the spark plug are new.

Ok first we are not waisting time here some info is needed to point you in the right direction ok. You said very little fuel came out of the filter. It sounds like the fuel pump quit working or the fuel pump relay

. Now on the fuel injection rail is the test port, with a fuel pressure tester is how you check fuel pressure. This is what the fuel pump relay looks like. Let know how it goes and we will go from there.
