You need to find out if you are getting spark or fuel.

So, remove a spark plug and crank it. Have someone watch the spark plug while you crank it.

If the injectors are working then the plugs should be covered in fuel after cranking.

Usually when an ecu goes bad you want have any communication w/ the scanner. And if the battery was completely dead it would erase the codes.
