Does bad coil packs keep fuel pressure down?

Bad coil packs do not directly affect fuel pressure, as they are responsible for igniting the fuel-air mixture in the engine cylinders rather than managing fuel flow. However, faulty coil packs can lead to misfires, which may cause incomplete combustion and result in poor engine performance. This can indirectly affect engine efficiency, potentially leading to a perception of reduced power or responsiveness, but it won't lower the actual fuel pressure in the fuel system.
