ok so im new to the mitsu world and def new to the forum. i bought an 01 galant es 3.0 automatic that had several issues with shifting problems and lots of sensor codes. i discovered that someone had put an 02 ecm in. so i got a used 01 ecm and intalled it and now it cranks but wont start. does it need to be flashed or is it junk? im kind of at a stand still. any advice would be awesome. thanks!
