Cadillac Seville 1978 engine turns over but does not start after replacing starter solenoid, distributor cap, and rotor on Cadillac Seville

Some 1978 Cadillac Seville owners report experiencing difficulties with their engines turning over but not starting after replacing the starter solenoid, distributor cap, and rotor. Common issues include a lack of spark, which may stem from problems with the ignition module, distributor, or coil. Additionally, fuel delivery problems can prevent the engine from starting, even after component replacements; potential culprits include the fuel pump, fuel filter, and EGR valve. Some owners also face cold start issues, where the car starts but dies immediately, possibly due to a malfunctioning fast idle valve. Furthermore, electrical issues, such as loose or disconnected wires under the dash, can significantly impact the vehicle's electrical system. It is advisable for owners to double-check all recent replacements, verify connections, and consider consulting a qualified mechanic for a thorough diagnosis to identify the exact cause of the starting issue.
