stalling, hard start, fuel pump/relay issues? read this!
Hi All,
Not exactly an expert but I have recently had stalling issues with my 2012 CRD GC. It started 2 weeks ago and the initial stall was sitting in Macca's drive thru waiting for my coffee. It occurred again when my wife was driving into town coming into a roundabout at slow speeds luckily. I checked and replaced the fuel pump relay with a standard 40amp relay and hooked up a mates scan tool. I could see a fluctuation of about 3000kpa pressure on the fuel rail. I booked the jeep in with the dealer for a proper scan fault diagnosis and to cut the story short a week later I'm down $3000 and have a new fuel pump module 1&2. The mechanic at the dealer believes the pump was sucking air causing the stall event.
I believe the relay recall and fuel pump issues are related and one has taken out the other. I believe the fuel pump failure could be considered as dangerous as the relay failure. I have contacted ACCC and they have shown interest in the matter and have asked for more info.
If anyone out there is experiencing similar issues let me or ACCC know.
Damn, I wish you had posted something earlier, I have both those pump modules sitting in my garage after a Stealership changed them out after a really questionable pattern of fault finding.
Thanks Buffomarinus but I dont think it was the pump after all. I checked the old pump and transfer module out today and I cant see the pumps being the issue. I will be bench testing them so I have a better understanding of what is happening and how they work.

So you paid for a new pump for nothing?

What was the conclusion to this? Did you determine the cause or do you no longer have the vehicle.
I do get the symptoms of almost "stalling" but never does the engine cut out. Usually happens when i'm waiting at the lights. I've had all those external relay recalls put in place for some time now.
