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.
