My mother is having issues with her trailblazer it'll start and
then it'll just sputter out and I'm thinking it's injectors or coil

Make sure it not a security system problem, if that checks good then check fuel pressure and flow. If that is good then exhaust system back pressure. If you haven’t found it then a live data scan might reveal the problem.
check for proper fuel pressure first. is there a fuel filter? maf clear?
