Check your harness and make sure there is a wire in connector A pin 20. A lot of homebrew and aftermarket harness's dont have this wire in the plug. V6 connectors don't use the fuel pump signal. If you don't have a wire to this pin, you can install a wire in this position and connect it to the positive wire on the fuel pump or disable the error code. The easiest way is to disable the 54 error code in the bin. If you can post your bin, and a datalog, it would help.

Can you explain to me how I go about posting my bin iam new to all this efi stuff thanks for the reply and will post my data log and bin soon

I guess I need to ask you some questions. Do you have a chip burner or are you just datalogging and sending your memcal to your tuner? What are you using to get your datalog? Are you using an ALDL cable and tunerpro? You will have to be able to read your chip with an eprom programmer to get your bin or you can ask your tuner to send you the bin file. Some tuners will not send a bin file though.
