Trucks also contain a number of fuses designed to prevent damage if components experience electrical surges. Using the owner's manual, drivers can locate the fuse box and check fuses related to the starter engine. Many fuse boxes have replacement fuses, and broken fuses are generally easy to identify visually.

Ignition switches also go bad. If the battery and fuses seem to function correctly, drivers should next place the key in the ignition and turn to the on position, which is normally right before the start position. If the dashboard lights up, the ignition switch is working correctly. If not, the switch likely needs replacement, which might require expert help.

A faulty starter engine can also cause a truck to not start. Starter engines have two wires connecting to them, and a voltage detector can reveal if the battery is delivering power to the starter engine. If it's receiving power but doesn't react, it likely needs to be replaced. However, it's important to exercise caution to avoid being shocked or having clothing stuck in the engine if parts begin to spin.
