Hard Starting Issue - Ford Mustang 2020
The vehicle is experiencing progressively longer cranking times before starting, indicating a developing issue in the fuel, ignition, or battery system. This symptom worsening over time suggests a component failure rather than a temporary condition.
Diagnosis Details
Possible Causes
Weak or failing fuel pump - The fuel pump may not be maintaining adequate pressure, causing extended cranking to build pressure.
Clogged fuel filter - A restricted filter reduces fuel flow, making it harder for the engine to start.
Failing battery or charging system - Low voltage can cause slow cranking and extended start times.
Faulty crankshaft position sensor - A failing sensor can delay ignition timing signals, leading to hard starting.
