S40 (New) Engine 2.0D : - Intermittent power lose resulting in not starting

jball · Feb 12th, 2011, 11:41

My volvo s40 2006 2.0d has developed an intermitting problem which it would lose power to the point of stalling but would then fire back up straight away. The other day however it failed to start and felt like there was fuel starvation, the computer diagnosic flagged up the EGR Valve which need to be replaced, after replacing this value the car would still not start. So i now been reduced to guest work, would a fault EGR valve prevent a car from starting firstly, and is it just a case that the system needs a good priming first, or is it the injector pump (as the garage has suggested) or blockage in the tank that would prevent the car from starting. Any help would be gratefully recieved as this is driving me mad.

Take the boost pipe off the very front of the engine and make sure the flap in the throttle body isn't stuck shut, I can't remember I'd the ECM requires an upgrade from Volvo after egr replacement or not. Marc

Thanks Marc for getting back to me

I check the throttle body on the morning that it would not start, but the garage have remove the fuel pipe to see if there is any fuel coming through the system and not realising that the fuel system is a vaccum line and just connect the fuel pipe back up with out priming the system so im hoping this may be the problem. I hoping the ECM does need an up grade though as im trying to avoid the main dealers.
