Hi all,
I own a beautiful Volvo XC90 and I love it to bits. It's just so smooth on the road and I love the 2.5T petrol engine. The sound system is just great as well.
I've started having some issues when it comes to starting it, but only sometimes. Sometimes I can jump in, turn the key and start it straight away. But other times it will cough and splutter, and sometimes it will stop cranking. But it's not the battery - I've put 3 different batteries into it. And it will start cranking again right away.
What I have found is that if I turn the key to On but wait before cranking it, you can hear the fuel pump prime for like 5 seconds or so. Then I can start it fine nearly every time - but 1 in 100 starts it still coughs a little bit. That's what makes me think it's potentially a fuel pump releasing the pressure when it shouldn't.
Once started, it runs perfectly! Super smooth and plenty of power.
I've tried searching online, and for similar issues, people suggest the fuel pump, the fuel pressure regulator, or the starter motor. I'm thinking the fuel pump is the most likely cause. I'm not quite sure why it stops cranking sometimes, as though the battery is dead, but then will start cranking again fine. Def not the battery, I've had 3 new batteries in it.
Does anyone here have any suggestions?
I'm also looking at buying an older Volvo... there's a gold 262 C on carsales I wouldn't mind restoring... but I need to get this one starting properly first! Any advice would be much appreciated!
