I have a 1997 Suburban which I am not getting spark to the coil. I have replaced the coil but still nothing. Any ideas?

Do you have primary voltage to the coil, key on, pink wire? Is it hot/voltage? Any applicable trouble codes? Some possibilities, coil driver module-- faulty wiring circuit, somewhere, Maybe the computer doesn't see a rpm signal? If that is the case, no injector pulse either. You can use a noid lite to check for injector pulse, engine cranking.
