My question is why were the lines and sensors replaced? The only reason they replace components like that is when something has gone wrong and metal shards of metal have gone thru the system and they usually replace everything including the injectors when they repair it.
Charles, when we purchased it the seller said it had leaks apparently so they replaced the lines mate all i know they gave me a reciept for the work done which was replace common rails fuel lines/ sensors.
Im looking towards injectors above issue could be the cause pump seems fine though . There is no metal present in fuel filter or imv filter but there may have been a failure in the past not sure on the history of the vehicle.
It's hard to determine just what they replaced but to fix a leak yes maybe. The injectors are very expensive and have a code that matches them individually to the cylinder with a good scan tool. You just can't go ahead and fit them expecting them to be right. If they did remove them and not fit them back into the cylinder they came out of that might be the cause of your problem.
We had the check engine light come on so went and put it on the snapon scan tool. Had couple codes logged. Injector/imv/maf/temp sensor codes. So we reset them and went for a drive until check light come on and went and put the scan tool back on and it only logged P1119 inlet metering valve control. I did bench test the unit was within spec and operated with 12v supply . Possibly leak maybe will replace the unit and see if that corrects the issue.
