2001 sunfire cranks wont start.
I put in a new radio..now rolls over 4
ever...wont start...itll start with starting fluid till
it burns out..no alarm light..I know it sounds
dumb......was it some radio thing?
So either the fuel pump just went out, or you blew the injection fuse during the install of the radio system, so check for a blown fuse first, and use a test light or remove then one at a time and ohm each one out, a visual check sometimes misses a blown one if it isn't right in the center. HTH
