ok, so after the wire tuck, fox throttle body conversion and battery relocation i have a no start situation. fuel pump primes, cranks normal, no spark. pulled plug to arc off header with no result, no spark off coil either. started probing, found no power at the coil, no 5v ref at the tps which made me suspect that the ecu was not getting correct power or ground inputs. moved on to checking connections at the ecu. reference diagram below:



hot at 57/37

ground at 20/40/60

no ground at 49

anybody know where 49 picks up it's ground? what other areas are worth testing?
