Replaced fuel pump in my 1997 ford thunderbird lx. Fuel pump is working car will not start. Any tips on trouble shooting?

yes....your startermotor wants to see at least three hundred cold cranking amps to get a move on...to deliver this amount of amperage we need NO interruption of the WELDING amperage....such that you need to get a NEW battery if yours is older than five because the tin/antimony alloy batteries (no lead no mo) will stop accepting a charge 10 percent per year....so the end of the 1/0 cable that connects to the chassis ground and the one that goes to the motor block (has a bolt on that near the alternator) need to be coarse wirebrushed clean to allow the full amperage potential and enough amps to make your starter say howdy-high~
