Hi, I have just joined the forum & hoping to get a steer in the right direction from the wise ones.
I bought an 07 JKU CRD 5 months ago, she's done 110k km & I love driving it but have run into a problem that I am struggling with.
At Christmas time I started intermittently seeing the check engine light with the following fault cods:
-P0193 (fuel rail pressure sensor circuit high input)
-P0088 (fuel rail/ system pressure too high)
The car would go into limp mode but if I drive for 5-10 minutes and restart full power returns (usually the light remains on but sometimes it clears)
This would happen 1 or 2 days a week. Several times the light has come on as I drove over a speed bump or dip in the road (coincidence or just a loose connection somewhere?)
My mechanic sought advice from Jeep (he used to work there) they suggested replace the fuel rail (sensor & rail supplied as 1 unit, you know the drill). Potentially it could also be a fuel pump issue.
We replaced the fuel rail with one from a wrecker (35000km) and it drove well for a week, then the same issue for a day, drive well for a week, same issue for a couple days etc. He was good enough to not charge me for the replacement fuel rail since it hasn't fixed my problem.
On 3 occasions over the last 3 months it has also cut out after setting off from a start, on these occasions the symptoms were like a flooded engine, wait a few minutes then restart and go.
So, I am looking for a diesel / Jeep gooru to get in there & advise me. It might just be a fuel pump pressure test, but who knows.
Can anyone recommend a Jeep or Diesel specialist for me? I am located on the Northern Beaches, I work in Brookvale (so anyone in Brooky would be great)
Thanks guys,
John
