i swapped in my sr20det in my 240sx and im having some wiring issues. i followed the frsport wiring guide and did everything exactly like they said. i was testing for power in my coil harness and i only get the far right pin to give power(i believe is the signal wire?). the same thing was happening with my tps. then i found a ground that wasnt being connected so i grounded it. the signal that i was getting from the tps and coilpack harness is gone but theres still no main power to any of them (im not even sure there is supposed to be ) the main problem is im not getting spark at all, iv changed plugs all coils and i just cant get spark. could this be a ground problem? a relay problem? im not a wiring guru in the least.

Test your relays they like to not work. jump the relay with a piece of wire, check it with a voltage meter if your getting better voltage you can rule out relays.

i have a project car that ran at one time so i know the relays work. im thinking of just switching out all those relays for the ones in my car. hopefully this works.
