What causes the 96 caprice classic Lt1 not to fire?

The 1996 Caprice Classic LT1 may not fire due to several common issues, including a faulty ignition system (spark plugs, wires, or ignition coil), fuel delivery problems (clogged fuel filter, failing fuel pump, or dirty injectors), or issues with the engine's sensors (such as the crankshaft position sensor or mass airflow sensor). Additionally, low battery voltage or a malfunctioning security system can prevent the engine from starting. Diagnosing the issue often requires checking these components systematically.
