Vehicle Cranks But Won’t Start

---

When the engine cranks but refuses to start, it’s easy to assume a fuel or spark issue—but assumptions lead to parts-swapping and wasted money.

At Keeney Auto & Diesel, diagnostics are done differently.

• ⚙️ Live-data analysis reveals if fuel delivery, ignition timing, sensor input, or mechanical integrity is actually to blame.
• 🔌 Power and ground paths are verified with voltage drop testing—under load, not on paper.
• 📊 Advanced diagnostic tools like in-cylinder pressure transducers, waveform analysis, and ECU command tracing isolate the cause down to the signal level.

Whether it’s a failing crank sensor, a stuck injector, or a module that stopped listening, root cause matters—and here, it’s found before parts are touched.

If your vehicle cranks but won’t run, schedule a diagnostic session and get answers—without guesswork.
