91' wrangler fuel problems

i have a 91' Wrangler-6 banger- that i think has a fuel pump problem. As i was sitting waiting for a train to pass, the jeep died. i pushed it to the side and tried starting it. It will crank, but just doesn't seem to be getting any gas. i repalced the in-line fuel filter, but it is still the same. i checked the relay in the fuse box-good. i took the tank-side line off from the filter and tried to crank it to see if any gas was pumping out-none (i know it's not the safest way to check, but i was alone). I'm not a "car" guy but everything seems to be pointing at the fuel pump-am i right? Is there something else i need to be looking at, or checking in a different way? If it is the fuel pump, is this something i can fix, or is it a "shop" repair? Thanks for any help guys!!!

Assuming you have gas in the tank.....Was there gas at the filter? Are you getting gas/pressure to the fuel rail? There is a service valve on the rail that looks kind of like a valve stem. Press the pin (being sure to have a rag there to catch any fuel) and it should pass some gas.

It has gas. When i replaced the fuel filter, gas leaked out of the line, but after all had drained, there was no more present. i tried cranking it, thinking that the filter was the problem-but it wasn't. When i took the tank-side line off again to see if there was gas present, i didn't find any. I will try the service valve up by the fuel rail. If it is a bad fuel pump, is this something i can change- i have some skills around a car, but i'm not a car-guy.

Pretty easy as long as you drain the fuel from the tank. Drop the tank down and there it is. twist the ring and pull out.
