Mazda 3 has intermittent starting failure; no dash lights when cranking fails, but battery tests fine and jump starting doesn't help, requiring multiple attempts to start.

Workarounds Described

• prays before starting the car
• tries cranking multiple times until it starts
• tested battery with a tester but still no start

Implied Software Gaps

• An app that logs electrical behavior during starting attempts to pinpoint intermittent faults
• A diagnostic tool that captures loss of dash lights as a clue for ignition switch or relay failure

IntermittentStart Pro

A mobile diagnostic app that logs cranking voltage, starter current, and ignition key position during each start attempt. It detects intermittent failures by correlating symptoms (no dash lights, no crank) with electrical patterns, guiding the user to the exact faulty component (ignition switch, starter relay, or ground connection) without guesswork.
