My tahoe cranks but will not start. Looks like I dont have and injector pulse and I need to know what is preventing that. I have a strong spark, the fuel pump runs and is producing sufficiant pressure. It will run for a second with a couple squirts of carb cleaner. Looking for a little guidance so i'm not chacing my tail. Will the crank sensor only produce crank signal instead of crank and fuel signal, am I looking at a computer or spider injector issue or something different all together. Any help is much appreciated.

Have you checked to make sure there is no pulse to the injectors? If so, and there is no power to them, start tracing wiring back to the PCM. Chances are there is a break in the wiring. Also, check to make sure the connector to the PCM is tight, clean, and not corroded or damaged.
