You need to check that you have power making it to the pump. Check that you get power at the relay when the key is bumped, if you have power there then you need to move to the inertia switch, power coming in and out of the switch. If you have power at both locations then the issue is between the switch and the pump.
Here are diagrams of the locations, you will need to look up the wiring diagrams in your book.

Not trying to be a dick but have you considered taking to someone w/ experience in auto repair? Sounds like you have a host of problems.

check your fuel pump relay under your hood first. Probably your problem.

+1 on the relay. do you have a multimeter? check the relay with your multimeter to see if its working. do you hear your fuel pump turn on when you turn your key? if the relay is working go to your fuel pump and use your multimeter for continuity. Thats what I would do. Good luck hope ya get that fixed... no stang = poooop
