Ford E-350 Super Duty not starting despite ignition light being on on Ford E-350 Super Duty

Some Ford E-350 Super Duty owners report experiencing starting issues despite the ignition light being on, which may be attributed to a failed ignition switch that fails to send power to the starter motor. Others have encountered problems with a malfunctioning fuel pump, resulting in insufficient fuel delivery to the engine. Additionally, troubleshooting these no-start problems often requires essential testing tools like a spark tester and a fuel pressure tester. Some owners note that the 'service engine' light being ON when the key is turned can indicate that the van will start, suggesting a potential connection to the starting issue. Furthermore, the intermittent nature of the fault, along with the presence of warning lights and sounds, may indicate a sensor-related issue that necessitates further investigation. It is crucial for owners to consider these potential causes and utilize proper diagnostic tools to identify the exact problem.
