mean green cobra

i wrecked my 96 mustang gt . so i took all my stuff if and put it on a 97 body that i bought . my fuel pump worked when i took it out of my old but now that its in the new car i cant get it to kick on. my tail lights are working . i used my drill battery adn jumped it to my fuel pump to see if it works and it did. i just cant figure out why i dont have power going to the fuel pump or even know how to fix it or wire it the right way. someone please help if u have ne ideas

Did you check the inertia safety switch in the trunk? It may be tripped and cutting power to the pump. Also check fuses & relays. Could also be the neutral safety switch on the tranny. The list goes on. Best advise I can give you is to get the electrical diagrams for your year/model ride and start poking around with a multimeter until you find the place where power goes in, but does not come out. Good luck...

There is no neutral safety switch on our cars. At least not the GT's or cobra's from 96-04. Most likely it's the Inertia Safety Switch, if not that I would check fuses, if not that I would check for loose/broken connectors and broken wires.

I'll just go ahead and beat a dead horse and say I would check things in this order:
1. Inertia Switch'
2. Fuse
3. Relay
4. Pull the tank back down and make sure you didn't mess something up. Not being a jerk, but 9 times out of ten if something worked before you mucked with it and doesn't work afterwards it's your fault.

There is if the car is an automatic. Yes, you could get a GT in an automatic.

Neutral safety switch powers the starter, not the fuel pump.
