Xc90 2.4 d5 failing to start but cranks
 

So my xc90 is failing to start, it stated when I broke down the aa came out and said that the high pressure fuel pump was knackered so replaced with a second hand one that was tested its 185bhp

The issue is its got all these errors and I have replaced a lot of sensors with no avail any help would be amazing

I tested with multiple diagnostic software Vida and launch

It’s looking like a fuel pressure problem there. What codes did Vida report, they’ll be more specific.
I’d be tempted to look at the fuel filter first and with that off check to see if the low pressure pump is working.

Hi all, Would be nice to hear what the solution to this issue could be as I have the same problem. Redone engine and now cannot get the car to start. Replaced fuel pump in fuel tank after we confirmed the previous one was knackered. Also had to check the flywheel /crankshaft sensor - replaced it.

Any update on this? I have a similar problem... started fine before I changed fuel pump and swirl flaps but now won’t start?
Any suggestions
Thanks
Tyler

When you replace the fuel pump don't you typically need to bleed the air or turn on fuel pump via key (but not crank the car- that humming sound I hear from the car for a brief moment just before I crank the engine I think is the fuel pump pressurising/working) so that fuel is making it past the fuel pump and into the fuel rails?

I have had the car tested via diagnostic laptop, showing full pressure to the rail, no error codes coming through at all the thing just won’t start!
Close to being done with it now if I don’t find a solution soon lol

Blow a bit of easystart up the air intake, if it fires on that (it will sound horrible), you’re looking at a fuel system problem. If not, it’s intake related.

This might help

Thanks for the help guys, still no luck, there is no mechanical reason as such (I think) as to why it isn’t starting,
Decided to start looking at glow plugs and fuses now...
Unless anyone has anymore suggestions
Cheers

Diesels are compression-ignition engines

If there's fuel, squirted in at the right time, and compression and the engine turns, it should run.

Glow plugs are to help cold starts - shouldn't be necessary in UK yet.

Have you tried the previously suggested squirt of easy start, as this will prove you have compression?

Sounds like something is inhibiting the actual squirt of fuel by the injectors - but I'm out of my knowledge depth after that.

have you tried bleeding one of the injector pipes at the injector? Might still be some air in the pipes.

Hi Dave,
I’ve used a full can of easy start trying to get it going and I’ve had absolutely no luck... with the easy start and pumping the accelerator I get a little bit of hope but after 3 seconds or so all power is lost, revs drop to naught and cuts out again,
I have someone hopefully coming tomorrow with a Volvo diagnostic kit to see if that picks up anything more than what I already know... I’ve had 3 mechanics (friends) come and diagnose a problem and mechanically they say everything is as it should be, all baffled as to why it’s not starting...
Due to never really working on a car like this before I have no experience to compare it to...
A diesel expert suggested a battery issue as the car had been standing a few months before me purchasing it but following his advice I still have no luck,
The car feels as though it wants to start, for whatever reason it just isn’t...
Thanks again all, if anyone has any other suggestions I’ll gladly try before this guy comes with a volvo diagnostic,
Cheers
Tyler

Hi John,
Yes done all this, no joy

I'm not an expert, but can it be the transponder? I've heard (and experienced) spooky things after battery outages.

Have you tried to do a battery reset (disconnect - wait - correct order to reconnect)? It's just an idea, as all "normal" things seem to be checked... :)

Good shout paddy. It know that ring aerial problems will give just such symptoms. I am sure this can be checked with Vida and certainly this would be my next step. Also have you tried another key?

Thanks both for response
Unfortunately for me yes to both your suggestions... i really am at the end of my wits with it I think haha,
I just feel as though I’m edging closer to drawing the line at throwing money at the thing if I’m honest,
I have a feeling it’s going to be something really silly or stupid as there are literally no faults on the reader, the work that’s been done has been stripped back and checked twice over...
My last hope is the guy comes tomorrow with his Volvo reader and it flags something up but I’d be suprised if it does..
Gonna keep going tinkering with it for now when I get chance
Thanks for the suggestions again 👍

Do you mean that it fires and runs a bit on easy start, but then stops running once the easy start has been used up?

Then it's clearly getting no fuel.

Check fuel lines and injectors.
Are you getting electrical pulses to the injectors?
Are you getting fuel to the injectors?

According to Vida it’s now a CEM water corrosion issue...
Something to to try I suppose!
I’m not sure how this would effect fuel etc as I haven’t really looked into but it I’ll be giving it a go

hi, get somebody to crank the engine over, open the fuel pipe at the injectors one at a time. the fuel should come out then lock it up and do the rest. that way you know your getting fuel up. if not you’ll have to look at fuel relays. is there a fuel cut off switch? This can be activated if the car thinks it’s been in a crash. are there any codes coming up?.
