2005 WJ Grand Cherokee 2.7 Diesel
I purchased the car in May 2012 and it ran fine until it was serviced in October. As part of the service the existing EDM fuel filter was replaced with a new EDM fuel filter. Almost immediately the engine became hard to start and would cutting out at speed when repeatedly put under load such as accelerating down a motorway slip road, lifting of the gas, accelerating again to get into the flow of the traffic and lifting off again. OBD also logged P1130 (fuel rail pressure problems). The fuel filter was swapped for another EDM, and then swapped again for genuine Jeep one, and the problems was cured until..…..
Early January the same poor starting and cutting out issues occurred again, but this time no fault code was logged. Starting was very poor but improved using ether/easy start. Did a leak off test and found No.4 injector was returning about 4 times as much fuel as the others. Replaced it. This made things a bit better, but not much:
- When the car has been stood for less than 12 hours it starts and runs fine.
- When it has been stood for more than 12 hours and the temperature is more than 5°C it starts badly, but does start.
- When it has been stood for more than 12 hours and the temperature is less 5°C it will only start with ether/easy start.
- And annoyingly it also cut out on the motorway again today.
Any suggestions gratefully received
