What does the EDGE say your FICM voltage is? if below 48v bad juju.
Replaced mine last year due to P0611 and injector codes, my voltage was running 35 on average till warmed up.
It should read 47.5 to 48 during key on, crank, start, and run.
Lot of info on FICM on the forum, do a search and you will find more than you want to know.
