Problem overview

Some Chevrolet Caprice V8 owners report experiencing engine stalling issues after starting, even after replacing the fuel pump and filter. These problems may stem from various factors, including complications with the fuel injection system, which can disrupt fuel delivery. Additionally, a faulty temperature sensor may lead to insufficient fuel delivery when the engine is cold, exacerbating starting difficulties. Owners also note that a lit check engine light indicates a hard fault that requires attention, potentially due to component malfunctions or wiring issues. Clogged fuel injectors are another concern, as they can hinder fuel atomization and contribute to engine stalling, necessitating cleaning or replacement. Furthermore, a faulty fuel pressure regulator may cause hard starting issues, making it crucial to check for leaks and ensure proper functionality. Lastly, problems with the EGR valve or carbon buildup in the EGR passages can impact engine performance, which may require cleaning or replacement. Addressing these components systematically can help resolve the engine dying issue in the Chevrolet Caprice V8.
