2010 Nissan Murano - Stalling on startup. Any help?!

[Starlight800]

Hey! Can anyone help with this issue I've got - wondering if any Nissan Murano owners have had a similar problem?

Its a 2010 Nissan Murano DCI Auto 2.5L (right-hand drive).

Basically, on cold startup, the vehicle stalls if I don't sit with my foot on the accelerator for 2 or 3 mins. After that, it's fine and will idle, but if I don't rev it up then it stall immediately.

If I then turn it off and start it up again within a couple of hours, it'll idle no problem. But then the next morning the problem returns.
A local garage has taken all the diesel injectors out and sent them for testing (they're absolutely fine), so he suspected there could be air getting into the system, but couldn't detect any anywhere.

It's only done about 115,000 miles so keen to get it resolved.
Thanks in advance!

Has live data / fault codes been explored?
Whatever the modern day equivalent of an automatic choke / fast idle device would be my first thoughts, but there is so much electrickery and senors involved that it's bound to flag up that a component is out of normal parameters.

Thanks for the reply. There are no warning lights, and no problems show when they plug it in for a diagnostic check. Mmmm, it's a mystery. The auto-choke equivalent seems to make sense. Thanks!

Parts for Muranos are starting to go out of supply from Nissan.
I had a customer try to get power steering pipes last week and they are no longer for sale. Other bits were 8 week back order.
With electics being mentioned I would be wary of parts supply going forward.

You should change your temperature sender first, it's the cheapest component in the stage to figure out why it only stalls when cold. This sensor is what fuels the car and it needs to know when it's hot or cold.

^^^^ Wot 'e said.

It sounds like the engine needs to be warmed up before it will idle.

This smacks of a temperature sensor input into the ECU.

TBH, when you said the garage checked for fault codes & couldn't find any gives me the shivers!

So they didn't check any live data or do any investigation/fault finding, they just checked for fault codes!

If I were you, I would be going elsewhere, it sounds like they are just "fitters" rather than competent mechanics.

You took it to a garage to have it diagnosed but they didn't do any meaningful diagnostics.

Now you're on the forum asking us to help. We don't have the car, can't look at it, plug in a scanner, etc.

OP are you willing to spend money on a scanner which can read live data off the car?
