96 ranger fuel system problem. - need help!!

:screwy: ok, This is diving me nuts. I'm not getting fuel at all. Before i figured the problem, i changed plugs, wires, fuel filter and now the fuel pump. After I tried to start it and it didnt work, i checked the emergency fuel pump shut down switch, thinking that may have tripped when i removed the fuel tank. no dice. so i shut the radio and everything off and turned the key forward, but didnt start it.....all i heard was a few clicks and that was it...the fuel pump was not pressurizing at all. So i check the Relay...again to make sure. and its fine. So i get out a test light to see if the pump is getting power, and i cant get into the wire harness to get a bite on positive and negative. But i think im at least getting power to the sending unit, because when I disconnect the harness - the fuel ga. reads that i have a full tank - when i plug it back in, it reads what is actually in the tank. (about 1/8) Someone please help...i really dont want to pay some jagoff towtruck driver to tow it to the shop and it ends up being something stupid. Thanks guys. :banghead:

did you test both sides of the inertia switch for power. if they both have power then check the fuel pump harness for power at the pump if there is power there then check the groung at the pump. i had a brand new fuel pump end up being faulty right out of the box. So good luk
