Diagnostic Tools - Ignition/Fuel/Starting Fault Finding

[SparkyNZ]

I have an intermittent fault with my 3.2 petrol non-turbo 2009 XC70

Every now and again it will crank for a long time before it will start.

I have replaced sparkplugs, coils, fuel injectors, fuel pressure sensor and cleaned a load of sensor connectors.

I'm wondering what to look at next.. and wondering whether it's worth buying something like the below:

Would the car record any instances of long cranking and offer some hints as to what may be wrong?

The car sometimes hesitates at lower revs under power (going up a steephill) as well.

I can't account for the ability of the iCarsoft unit although I emailed their customer service 're a Smart car application and never received a reply.

I use Vida and others on here will no doubt advocate the same. It's the Volvo oe diagnostic system

're your fault. Is that a hot or cold start?

Interesting that the eBay listing says Vida Dice in the title when it isn't.
They've included that misleading title because Dice and Vida s the one that people actually want and need.
If you have a suitable laptop and want the best chance of resolving your issue get Dice and Vida.
Parts catalogues, workshop manual, technical data for components, fault code reading for all modules.....

Evening , I would look at cam and \ or crank sensors . You sometimes remove them and find the end of the sensor covered in rubbish , remove ****e GENTLY with paper towel or soft cloth , replace and see how everything goes from that point onwards . If you know a friendly mech , ask them nicely to read live data from those sensors to ensure they are producing the correct waveforms that the ECU can understand & work with .

Hope that helps
