fuel pumps kicks on but no gas pumps out, what could the problem be

If fuel is not reaching the engine, in cases like this I replace the in line fuel filter first, the problem have been caused, in most instances, by a clogged fuel filter.

fuel filter is new, we pulled the line on the top the goes to the engine and no gas is coming up but pump turns on

Check the line that goes to the filter, coming from the fuel tank, if no fuel is flowing, then the problem is at the source, the fuel pump. I had that situation a few times, although the pump gave a sound as it was running, actually it had lost pressure. It will be necessary to check the fuel pump.

new pump and i checked to make sure everything was hooked up right, could one of the line attached to the pump get clogged. and how do you gain the pressure back

Yes, I have seen fuel lines get clogged by dirt from the fuel tank. Ryan is correct in thinking that the wires on the pump may have been installed backwards, even though you think it was hooked up right; double check.

ok so i checked all iline on the fuel filter. every thing is good, nothing clogged. i can even suck gas out through the line on top of pump. any other thoughts

Did you check to make sure that the wires in the pump were installed correctly, that the pump is not running backwards like Ryan says?

yes, all wires are correct, no way to hook them up wrong.

direct replacement ,

my car also dont want to run and pump was replaced

Did you prime the fuel lines? Open the glove box so you can be sure your fuel relay is working. First: Turn it on to accessory position not all the way to ignition., listen for the pump to prime. When you hear then you know you have the fuel fuse and relay and pump all working then turn it back off. Repeat turn it on and off like this 5-7 times. It primes the pump. Then try turning the key to start the engine.
