Help Car wont start.
2006 XC90 Manual D5 185.
I have had this car for about 4 years, it is an awful looking yoke with its mismatched mirrors torn seat and bad spray job on the rear door but it has always done its job. which is get me and my stuff where ever I want to go... I don't use it much so it often sits unused for weeks at a time, until last week it always started, sometimes it may need a restart after a few seconds and then it would be fine. I went to move it last week and the battery was low and it would not start, I charged the battery and still no start. turns over fine but there is no attempt to fire. Fuel being delivered to the high pressure pump and there seems to be plenty of fuel at the injectors. I sense it is an electrical problem, I have tried two original keys and locked and unlocked with no issue. I have tried VIDA and i cant see any faults which should prevent a start. ( several about the cabin temperature, brake pressure, and a few random about the 4wd gubbins on the back axle etc. its a new to me version of VIDA and I was not able to get any live data like RPM etc I was hoping to see if the crank position sensor was operating, if this can be seen on VIDA can anyone give me instructions on how to see it. Are there any suggestions on what I might try? all modules came up as available on VIDA so dos that rule out a bad CEM? |
Has anyone got a suggestion, car still won't start.

If you have enough juice and fuel is at the injectors what else is there it should run, shouldnt it even if running poorly? I wouldn’t know how to check but surly it has to be one of those.

I would perhaps post this in the v70 section there is much more traffic and your more likely to get a response.
|
Glow plugs?
|
What rail pressure have you got? If it doesn’t have rail pressure it will never run.
|
As said if you have fuel at the injectors then only thing stopping it is electric signal to injector to fire. As fuel pump is running I doubt is immobiliser so I would check the wires to the ECU. If you are confident, disconnect the battery and unplug the ECU connectors and check all clean and dry. Also check if any other wires in the engine bay have been dislodged or damaged.

Maybe the battery has just died or a cell has failed?

Am I in the correct screen in VIDA? When I try to start I am not seeing any movement in the rev counter is this a clue that there is an issue with the crankshaft sensor? Plenty of fuel in the car and the in tank pump sends plenty of fuel forward when the key is turned and a fuel line is taken off the high pressure fuel pump.. |
