Poor starting xc90 d5 2003

Johnboyzx10 · Feb 6th, 2020, 07:31

Hi please help . My d5 xc90 as just started to take ages to start in the morning.. like it’s turning over but will not fire sometimes this makes the battery flat .. it’s like the fuel is draining back every day and takes ages to start . Be for this it started after within 5 seconds .. glow plug light works .. it’s as if there is no fuel there every morning.. does any one know of this or a fix thanks john

Injector problems is the classic non-start issue on earlier XC90's, but it could be may things. It could also be a small air leak in the system, as you suggest, allowing pressure to drop, but even if that were the case it shouldn't be too severe and should prime itself long before the battery goes flat.

First step I think is to read the fuel pressure when cranking from cold. If the build up is really slow and the car only starts when a certain pressure is reached, next step is a leak back test on all injectors.

Search You Tube for diesel leak off test.

Another check is when it started do you get a cloud of smoke from the exhaust - if so it's more likely glowplugs (diesel being injected but not igniting and building up).

Does seem to be worse when it’s cold and yes big puff off white smoke when it starts after a bit .. runs fine all day then till next morning.. ?

Sounds very like glow plugs. We had some fail on a Renault and the replacements were sent were the incorrect voltage (the system was set to 7v and they were 12v) so it was fine in summer but a nightmare come the cold weather. Fine when warm and a clod of white smoke when it eventually started. It was made worse on that car by the fact it was push button start and it would only crank the engine for a set time.
