Okay, we need to start somewhere, so let's review the basics. Internal combustion engines require three things to run:
- Air
The air part usually isn't the problem unless your air filter as been filled with dirt by an industrious squirrel. However, with the advent of mass airflow sensors and throttle bodies, significant air leaks between the filter and the manifold can cause problems. - Fuel
On fuel injected vehicles, the individual injectors need power to turn on, and there needs to be pressure in the fuel line, so both of those things have to be checked. - Spark
The general method here is to pull a spark plug, reattach the wire and ground the tip to the engine block. Crank over the motor and visually check to verify that a spark is jumping between the electrode and the tip of the plug.
Of course, with the addition of computers in a vehicle, that system can itself keep any one of those three things listed above from working. However, it also comes with diagnostics in the form of the OBD-II port. If you have or can borrow a scanner, reading those codes can give you valuable information in diagnosing why your Tahoe won't start.

Hi lani,
What makes you think a fuse is at fault? There are a huge number of reasons why a particular vehicle won't start, but in order to help you figure out what's wrong with yours, we'll need a lot more information.
For instance, what do you mean by 'isn't starting'? Does the starter crank or not when you turn the key? Do the headlights work okay, meaning the battery has power? If the starter is working, does it simply never start up, or does it start and die immediately?
Getting answers to some or all of these questions will help point us in the right direction toward helping you get your rig running again.

@l1stunna "wont turnover all the way the starter cranks but wont turnover all the way" not sure exactly what you mean by that. Does it crank over just does not start?
