Troubleshooting Volvo Vehicles That Won’t Start
You’re not alone if you’re experiencing trouble starting your Volvo. Whether it’s a Volvo V40, XC60, S80 XC40, or V70, there are several potential reasons why your engine won’t start. From a lack of power when it’s hot to trouble starting in cold weather, several potential causes could be the culprit. In some cases, the engine may turn over but not start or make clicking sounds instead of starting. In this article, we will explore the common reasons why a Volvo engine may not start and offer some solutions to help you get back on the road.
Other problems include Volvo’s refusal to turn over, especially in cold weather, the key getting stuck, or immobilizer issues that prevent the engine from starting. There could be several reasons why a Volvo won’t start. Some common reasons include the following:
- Dead Battery: The battery could be dead, or the connections to the battery may be corroded.
- Alternator Issues: The alternator may fail to charge the battery, which could cause the vehicle not to start.
- Fuel Delivery Problem: The fuel pump may not deliver fuel to the engine, preventing the vehicle from starting.
- Ignition System Issues: The ignition system, including the spark plugs, ignition coil, and distributor cap, could be causing the engine not to start.
- Starter Motor Failure: The starter motor may fail to turn over the engine, preventing it from starting.
It is important to have a professional diagnose the issue, as they can perform tests to determine the exact cause of the problem.
Troubleshooting a Volvo that won’t start
First, you need to make sure you have a fully charged battery. Just because the lights turn on doesn’t mean the car battery is fully charged. A weak car battery is the most common problem preventing your Volvo from starting.
In many cases, the dashboard lights may come on, which can be misleading because it makes you think the car battery is fine. Ensuring your battery is fully charged is the first thing you should do. If it is not, follow these instructions to charge a Volvo car battery. Other problems that will prevent your Volvo from starting include:
If your Volvo won’t start, but the lights come on, the battery is often the problem. A flat or weak battery is one of the most common problems preventing a Volvo from starting. Watch the dashboard lights as you turn the key to confirm that the problem lies within the battery. If they are dim in the ON position or go dim when you turn the key to START, then the battery on your Volvo is probably bad.
Before doing anything else, visually check the battery. Corroded battery posts or the cable clamp is not snuggly fitted can cause a voltage drop and prevent your Volvo from starting. The next step is to try jump-starting your car by using a jump starter or borrowing electricity from another car with jumper cables. Be careful not to mix positive and negative terminals while doing this!
If this helps you, don’t forget to investigate why the battery drained in the first place. Maybe something such as a stereo or lights was accidentally left on. Otherwise, your battery might go bad, or your car may have a parasitic drain.
If you need to replace the battery, follow this guide to replace your Volvo battery. Also, it is possible that the alternator is not providing enough charge. Checking the battery voltage with a multimeter will reveal a lot. You should get at least 12V across the battery terminals with the engine off and around 14V with the engine on.
Central Electronic Module
The connections at your Central Electronic Module or CEM could be corroded, preventing the engine from starting. If you have been having intermittent electrical issues, such as wipers randomly turning on, for example, CEM could be the problem.
The CEM module could also be the culprit if your Volvo doesn’t start in extremely cold or hot weather. This guide explains common Volvo CEM electrical problems.
Bad Starter
Another possibility is that the engine starter is bad or seized. Tapping the starter a couple of times with the mullet may allow you to start the engine a few more times.
Defective Key
Volvo has transponders in the keyfob. It is possible that Volvo’s immobilizer does not recognize the key due to a bad transponder. Even if the key fob unlocks the car, the key may still have a bad transponder chip.
Although this will prevent a car from starting, it is usually accompanied by a crossed-out-key light on the dashboard. If you have an intelligent Volvo key, a weak key fob battery can prevent the car from starting. Follow this guide if you need to replace the battery in your Volvo key fob remote.
Shifter Position
To start a Volvo with automatic transmission, the shifter must be in Park, and the brake needs to be applied. Cars with manual transmission require that the clutch is pressed to crank the engine.
The Volvo engine turns over but won’t start.
If experiencing this situation, you should press the throttle pedal while starting a car. This can help in cases where the idle control is not working correctly.
No fuel
A bad fuel pump can prevent your Volvo from starting. The fuel pump is located in the fuel tank, under the back seat, or on the trunk floor. Have somebody turn the ignition on while listening for a buzzing sound indicating a working fuel pump. If you can’t hear anything, the chances are that the fuel pump is dead. Check the fuel pump relay, as that can also be the culprit. To verify your fuel system is working correctly, perform a fuel pressure test by connecting a Fuel Pressure Gauge to the Schrader valve located on the fuel rail on top of the engine. Other possible causes include the following:
- Clogged fuel filter
- Bad Key
- Fuel Pump Relay
- Immobilizer Defective
- Seized engine
Read DTC Codes
As modern cars are loaded with various sensors and other sophisticated systems, Volvo no start scenario can be caused by many possible faults.
A Volvo all-system scanner is the only reliable way to narrow down the problem. The YOUCANIC Full System Scanner can read and clear fault codes through every vehicle’s control module.
Conclusion

- faulty ignition coils or leads,
- crankshaft position sensor
- dead fuel pump.
If your Volvo doesn’t start, make sure to check the basics items. Poop up the hood, and check all the connectors and ignition leads to see if they are unplugged or loose. See if all the intake hoses are in place and don’t have any cracks on them. Do the same with fuel lines, both in the engine bay and underneath the car.
