4 Reasons Why Your Volvo V70 Starts Then Dies (Find To Fix)
Several underlying problems can cause you to discover that your Volvo v70 starts and then dies right after. However, most of the time, it’s a handful of components malfunctioning.
When a Volvo v70 starts and then dies, it is usually due to a failing signal to the fuel pressure relay, a contaminated fuel injection system, or a malfunctioning MAF sensor. Also, having immobilizer issues for inconsistent fuel delivery can lead to stalling in Volvo v70.

Here’s What To Check If Your Volvo V70 Starts Then Dies
I’ve listed down 4 major scenarios that are usually the case with a Volvo v70 failing to keep the engine ON after starting.
#Issues 1: Fuel Pressure Relay Not Getting Signal
Volvo v70 dies right after starting is often a straight sign of a failing fuel pressure relay. This means the needed signal is not available for the relay for the right fuel pressure maintenance.
As a result, the engine starts stalling right after starting. Only with manual relay operation, the engine run, which is again an indicator of signal supply trouble.
However, if your Volvo v70 starts then dies then turns off, it can also happen due to lack of fuel. You may find fuel in the rail but still, no pressure for the engine to keep running.
A malfunctioning camshaft or crankshaft sensor is a possible culprit. You should also consider checking the camshaft sensor display for any problematic resistance values.
This can also lead to engine timing disruption as well as issues with fuel delivery. Especially if your Volvo v70 starts then dies while driving it around.
Replace The Camshaft Sensor
If you find any abnormal readings, consider replacing the indicated sensors. This should revive the signal supply and also restore the stable operation of the engine. Based on cost approximations provided by Repairpal, this will cost you around 181 to 244 dollars.
Clean and Reseat Connections
Failing signal transmission to the fuel pressure relay can mean the connections between these two are corroded or dirty. Clean the parts and make sure to reseat them correctly.
Replace the Fuel Pressure Relay
A damaged relay can also disrupt the fuel delivery and engine performance leading to this problem. It will need replacement as soon as possible. Along with this, you should also check the fuel pump relay, the fuel pump itself, and any connections within.
#Issues 2: Dirty Fuel Injection System
Once your Volvo v70 starts and then dies automatically, in this scene you should consider using a fuel pressure tester and monitor. So that you can check the pressure when starting the car.
Sometimes due to contaminated fuel, the fuel injection system is disrupted, making the vehicle stall.
According To Bizol, apart from stalling or unsteady idling, you will also notice speed fluctuations and vibrations in the engine as strong indicators of contaminated fuel.
Clean The System
Get rid of any dirt and debris in the fuel system to restore proper fuel delivery. You will require cleaning or replacing the fuel filter. Also, consider draining and cleaning the gas tank. All these combined efforts should resolve the problem.
#Issues 3: MAF Sensor Can Be Responsible
The erratic start of V70 can also come from one or more sensors misbehaving. I would focus first on inspecting the MAF sensor, also known as the Mass Airflow Sensor.
If this sensor is at fault, you will also notice an increase in RPM along with the stalling issue. Especially during cold temperatures.
Replace The Sensor
A damaged sensor will need to leave the system. However please realize the nature of this fix, as it can actually alleviate the problem if not handled correctly. For this issue, you should consider getting a professional replacement if you are not a mechanically inclined person.
Keep In Mind – When replacing the MAF sensor, be careful with using rebuilt options. There’s a reliability concern related here that you should not take lightly.
Also, when cleaning this sensor, many make the mistake of using products not meant for it. Let’s say for example a carb cleaner. You should always be wary of these components, and go in with a MAF-specific cleaner.
#Issues 4: with Fuel Delivery Despite Sufficient Pressure
As I mentioned earlier, any disruption within the fuel delivery system can lead to a situation where your Volvo v70 starts then dies then stops for an extended period. And again, the lack of fuel pressure is what usually causes this scene.
However, if you discover that the system has sufficient fuel pressure but still the engine stalls, issues can be within more complex areas. I would doubt the immobilizer first here. If you don’t know what is a Volvo engine immobilizer, here’s a brief.
Volvo engine immobilizer is basically a security feature that requires a chip that contains an electronic code integrated into the key. As soon as the ignition is on, it will run to unlock the engine.
When I was discussing the start prevented error in xc90, the immobilizer was a potential troublemaker there as well. So, this is actually a general component that can be responsible for start related errors in any vehicle almost.
If not the immobilizer, then vacuum leaks can also be responsible.
Replace the Immobilizer
If you find the immobilizer to be guilty, it’s best to replace this part. This is because the part contributes towards the security of your vehicle. And you should not take any chance here.
Repair or Replace Vacuum Lines
Look for any tears or disconnections for the vacuum lines. Once you isolate the problematic line, repair the leak or even better replace it.
Wrapping Up
Now that you know why the Volvo v70 starts and then dies and which parts to have a look at, I hope you won’t be having more trouble. However, it is often a very specific issue that can vary from person to person.
So, if you soon realize the issue is hard to detect, don’t delay calling a professional. Start-related errors in Volvo can also be a sign of terrible engine issues. And in that case, you must find out appropriate solutions before it’s too late. Nobody wants to deal with expensive engine replacements after all. I will be back with more Volvo information. Meanwhile, why don’t you find out where the Volvo v70 is made?
