Car won't start/just completed FAST install

i just completed my FAST system installation today and car will not start. the starter will not do anything,no click,nothing. yesterday it turned over fine. the only thing i did today is wire my fuel pump to my FAST system.i checked all fuses and the purple wire from 4 pin connector on the passenger kick panel is not recieving any signal to the starter.you can hear a relay clicking under the dash when the key is switched on. i checked the clutch switch and it seemed to be fine.does the fuel pump wiring control any of the start functions?any help would be appreciated

Might be VATS not sending the signal to the PCM. Did you scan for a trouble code? See of there is a code 46 stored.

Are you using the original FAST or the XFI? You may want to try the GN forums as there is a big group of guys there w/ there own dedicated section for SA units.

Edit, I went back and loked at the schematic.... and yes the big purple wire does go through the VATS system.
