Speed3 Not Starting

The red wire is just a example of the passenger frame box channel that motor mount body base sits on. A ground stock one, if I remember goes from that frame box channel to bracket for TMIC corner. You just need to make sure a good ground exists there.
The fuel pump bracket is atop HPFP. That has the most important ground....the brass terminal one that goes to ground wire harness from coil wire loom atop engine cover. It has to be somewhere or you aren't going to start
