89 mustang gt fuel problems
I have a 89 mustang gt in the middle of the engine change. the problem i am having is that i replace the fuel pump relay under the seat and the only way the pump will cut on is the by pass the relay. even when bypassing the relay the fuel goes in the lines but nothing works with the injectors. i know i have more than one problem and at the point i am looking for help on what to try or look for so i can finish this project up. not sure where grounds are located at. thank you for anything in advance that could help me.
