2005 (54 plate) intermittent starting issue.
Hey helpful folk I hope your all OK,
I'm looking for some advice I have a 2005 volvo XC90 2.4 auto and I recently had it in for a gearbox flush and major service after the dreaded Transmission service required hoping it would go away, well.... whilst the garage is doing the gearbox flush they lost all communication with the whole car.. After days of fault finding they managed to narrow it down to the rear diff module had completely fried, so they unplugged it and communication came back so the service was completed, (rear diff unit now replaced for brand new part by a volvo specialist) however, I now have a however since picking it up from the service its had a intermittent starting issue. So basically sometimes it starts sometimes it doesn't. Most likely to start first thing in the morning but after a 15 minute journey to a petrol station or school run.. Will not start. Car turns on everything lights up, cranks but won't fire, other times a few tries getsbit to fire. The car has two faults showing #1 transmission service required (lock up function slipping or not engaging) #2 anti skid service required (break pressure switch fault) Can these issues cause this starting issue in anyway? The only giveaway I have noticed is when it's going to fire I have airnah, oil pressure light showing along with emissions system light, however when it's not going to start the only light that stays on is the airbag light.. 9nce the car fires all lights go out as usual. Any insight or thought process is welcomed as I'm am bemused. I have videos of when it fies and when it doesn't is that helps? |

Thanks Clan for your reply. so after some more investigating.. had all the fuel return leads off and injector 1 (first from the left) had no fuel built up and nothing dripped out when it was removed however injector 2,3,4,5 all had fuel visible. injector 3 had the most built up. so after a bit of playing around I have realised that ones ignition is turned to position 2 sometimes the oil pressure light does not come on and the car will crank but not fire but if i leave it in position 2 for around 3 mins the oil pressure light will come on and then the car will fire straight away? Any other ideas to look deeper into would be very helpful. |
