GMC Sierra 2500 cranks but won't start after new battery, starter, spark plugs, and wires on GMC Sierra 2500

Some GMC Sierra 2500 owners report experiencing starting issues despite cranking the engine after replacing the battery, starter, spark plugs, and wires. These owners often encounter fuel delivery problems, where issues with the fuel pump or injectors prevent the engine from starting. Additionally, some report ignition system problems, noting that faulty ignition coils or a malfunctioning ignition control module can still cause starting failures even after spark plug and wire replacements. Others have experienced concerns with the starter motor, where a faulty replacement can lead to cranking without starting. Electrical system malfunctions, such as loose connections or blown fuses, have also been reported as potential culprits affecting the starting process. Lastly, issues with the engine control module (ECM) or sensors like the crankshaft position sensor can contribute to these problems. Owners are advised to systematically troubleshoot these areas or consult a professional mechanic if issues persist.
