Volvo 780 Guides

FAQs—Volvo 780

I've been having a hard time starting my Volvo 780. It only cranks over, but it doesn't start and run. This is the first time it has happened to me since I bought my vehicle two years ago. What should I do?

Your car's failure to start may be due to a worn out fuel pump relay. This part is responsible for controlling the current received by the fuel pump whenever you start or shut down your vehicle. When this part fails, you will experience a "no start" condition, wherein the engine cranks over but it will not proceed to start. When this happens, the first step to address this problem is to check whether your car is receiving proper fuel pressure. If it doesn't, then you might need to replace your failed fuel pump relay with a new one to enable your vehicle to properly start and shut down again.

I never knew that my Volvo 780 has problems not until the engine stalled on me. I was driving on my way home when it did, and I was shocked because I didn't know that it has a problem. I've been taking the effort to maintain it every month, so I didn't see it coming. What could be causing my engine to stall?

If you have been experiencing engine stalling or stumbling problems, then there must be a problem with your mass air flow (MAF) sensor. When this part fails, your vehicle might not be able to find out the mass flow rate of the air that enters the engine. This information is necessary for the engine control unit or ECU to ensure that correct fuel mass is being delivered to the engine. When this happens, you need to replace your MAF sensor immediately to bring your car back to its working condition. You might want to bring your vehicle to your trusted mechanic for replacement.

Lately, I've been experiencing difficulty shifting my transmission into overdrive. It just doesn't engage. I own my car for already four years now, and this is not the first time that it happened. There have been several attempts to fix this by my trusted mechanic. Still, nothing worked. I wonder what's wrong with my vehicle. Is there anything I should replace?

If your overdrive has stopped functioning in your vehicle, then probably your transmission overdrive relay has failed. You need to check the solenoid and wirings if they are still intact and in good condition. If not, then you might need to replace the entire transmission overdrive relay with a new one. If you ignore it, you will have problems shifting your vehicle into overdrive. There is also an available solenoid block of kit that you can use for your replacement. The kit bypasses the entire system, and allows your transmission to automatically shift in and out of overdrive. If you use this, you don't have to use the overdrive button on the lever to shift down whenever you are towing or driving uphill.
