Why won't my rover 416 start?

There could be several reasons your Rover 416 won't start, including a dead battery, faulty ignition system, or fuel delivery issues. Check the battery connections and ensure it's charged; if the check engine light is on, diagnostic testing may reveal further issues. Additionally, inspect the fuel pump and filter for blockages or malfunctions. If these steps don't resolve the problem, it may be best to consult a professional mechanic.
