you mean ecm? low voltage on the maf may be a hole in the air duct after the maf. the only step i know of when hooking up a new computer is turn the key on and try to start. Check your fuses under hood though it may have blew a fuse. the new computer may have been flashed wrong too. alos check the engine for codes as youmay have a badcam or crank sensor. they can go bad and not show a code so you'll need to check resistance.
