It sounds like you did a lot to the car and it could be a lot of things

Replaced coil pack (why?)

Blew out and replaced the MPI relay (why did it blow up in the first place?)

Relocated battery into the back (did you add an extra fuse? how did you relocate it? what wire? did the positive ground out anywhere causing these problems? How did you connect the positive wire in the front of the car?)

Rewire fuel pump? (how do you blow the MPI by doing this? Also how did you rewire your fuel pump? Relay by the battery?)

Rewired TPS (did you check this with mmcd or some other diagnostic tool to see if it is working? ECU may not let the car start if it doesn't see a signal. )

On my 255 I know you can hear that for sure. What fuel pump are you running that you need a AFPR?

I am wondering because you blew your MPI relay and fuse, is the ECU far behind of being wrecked? By chance where did you run the wire for the battery relocation?

For right now I would make sure that the battery relocation is done properly. Make sure it has all the fuses in the right location. Then make sure that the rewire to the fuel pump is correct. All it should be is a relay controlling power from the battery to the fuel pump (again make sure everything has a fuse).

Then further test to make sure the ECU is working also the MPI again then the TPS.
