I have recently purchased a 58 plate pathfinder mammoth aventura. Lovely truck but has starting issues.!! Nine times out of ten it starts, sometimes hesitantly. But then it just locks up and won't turn over. It has a new starter, battery and egr unit. It all points to faulty injector/s as this is about £1,000 to have them rebuilt i wonder if anyone on here has had the same problem?? Thanks in anticipation
