What year Blazer? Do you have spark at the coil (hook up a plug wire directly with a grounded spark plug)? If so, do you have fuel pressure when turning the key on (correct amount ~ 55psi+, without engine running) and are the injectors being driven (use a noid light at the injector connector). Answer these things and we can go in the right direction to get it running.
