2020 S60 T5 No Start Condition - Cranks but Won't Catch

Vehicle: 2020 Volvo S60 T5 Momentum

My 2020 Volvo S60 T5 Momentum suddenly won't start. It cranks strongly, but the engine just won't catch and fire up. It was running perfectly fine yesterday. There are no warning lights on the dash, and I haven't noticed any strange smells or sounds.

I've tried cycling the ignition a few times, and checked the battery terminals, which seem secure. I'm wondering if it could be a fuel pump issue or something with the ignition system. Any ideas on what I should check first? I'm stranded at home and need to get this resolved.

ClearTheCode admin answer:

A 'cranks but no start' condition on your 2020 Volvo S60 T5 typically points to a lack of one of the three essentials for combustion: fuel, spark, or air (compression is less likely to fail suddenly across all cylinders). Since it cranks strongly, your battery and starter are likely fine.

Common Causes:

  1. Fuel Delivery Issues: A failing fuel pump, clogged fuel filter (less common on newer Volvos), or a faulty fuel pressure sensor can prevent fuel from reaching the engine.
  2. Ignition System Problems: A bad crankshaft position sensor or camshaft position sensor can prevent the ECU from knowing when to fire the spark plugs. Faulty spark plugs or ignition coils are less likely to cause a complete no-start across all cylinders simultaneously but are possible.
  3. Immobilizer System: A fault in the vehicle's immobilizer system (key not recognized) can prevent the engine from starting, even if it cranks.
  4. Engine Control Unit (ECU) Issues: While rare, a faulty ECU could prevent proper engine management.

Troubleshooting Steps:

  1. Listen for Fuel Pump: Turn the ignition to the 'ON' position (without cranking) and listen for a faint hum from the rear of the car. This indicates the fuel pump is priming. If you hear nothing, the pump might be failing.
  2. Check for Codes: Even without a Check Engine Light, a pending or stored code related to the crankshaft or camshaft position sensor might be present. Use an OBD-II scanner.
  3. Try a Different Key: If you have a spare key, try starting the car with it. This can rule out an immobilizer issue with your primary key.
  4. Check Fuses: Consult your owner's manual for the location of fuel pump and engine management fuses and check them for continuity.

When to See a Shop:

  • If you confirm the fuel pump isn't priming.
  • If you get codes related to crankshaft or camshaft position sensors.
  • If you've checked the basics and the car still won't start.
  • Diagnosing fuel pressure, spark, and sensor signals often requires specialized tools and expertise that a professional Volvo technician will have. They can perform a full diagnostic scan and pinpoint the exact cause.
