Hey, guys. :) I recently swapped a 1zz along with its 6-speed from a 2000+ Celica in my 2001 Corolla hatchback, because my 3zz blew a piston. Mechanically, everything is ok, more or less, however when I try to start it with the 3zz ecu (having read it's self learning enough to run a 1zz), the fuel pump doesn't run, there is no spark, ergo it won't start. Does anyone know the issue, or has an idea what could be a problem? Thanks in advance. :)
