My car takes a long time to start when cold or even if it has been more than just 30 minutes or so since I shut it off.
Cranking for 4-5 seconds then a stumble start, then runs fine. Fuel pressure reads 55 psi steady on the scanner.

I know the trick of cycling the key on/off a few times to charge the fuel line, and this does work but it bugs me
to have to do it.

The stumble start I believe is the reason for my P1582.

I also believe my fuel pump works ok but the check valve which is integral to the pump has failed and wont trap
fuel in the fuel rail as it should.

So after all that I have two questions. 1. I have read only a dealer can erase a P1582. Nearest dealer to me is 2 hours away. Has anyone found another way to erase a P1582? 2. Read somewhere on this vast forum that it was easy-ish
to install a separate check valve in the fuel supply line downstream of the fuel pump. Is there a how-to for this job?

Changing the fuel pump is such an ordeal on the convertibles. If we could put together
a procedure for adding a check valve it might save a lot of $$$ or labor involved in pulling the tank etc.
Thanks

 

I don't think it matters if you leave the P1582 as it doesn't turn on the MIL and so should not be a problem - do you think that it is a problem and if so why?

 

P1582 is the EDR (Engine Data Recorder)

Clearing it now will not matter. But if I can get my long start issue fixed I would like to be able to clear the 1582
so that if it comes on again in the future I will know to look at the six different things that might set the 1582 code.

 

Thanks for the link. Great info.

 

I don't know which if any non-OE tool can clear it, but the OE ones can.

 

funracer,

Long shot - as P1582 is related to certain conditions, the identified cause of your problem could be your inertia kill switch?

 

Yes that is on the list of causes. But I am having a stumble start nearly every time which is also on the list, so I assume that
is the cause.

But lets suppose it was the inertial switch and resetting it fixed the issue. Would the 1582 disappear on its own or have to be cleared? If it does not go away on its own how would I know if the inertial was tripped? So I think its important to be able to clear it.

Looking for the cheapest OE device that will clear this type of code.

 

I don't know if the EDR stores the info for a set time period or 'drive-cycles' and then clears itself? I doubt that it is the case.

There are TWO separate EDR event logs (A & B) 37 frames each as well as the start time reliability log.

You can read them and upon exit the menu will include the option to exit without clearing or 'clear all data recordings'.

Then when you go back to the ECM, you can read and clear again and the P1582 will be GONE if you chose to clear the data.

Which OE device do you recommend to handle this kind of thing? I currently have an iCarsoft V1.0 which I do not believe will do it.

Thanks

 

Since I worked at the Jaguar dealer and I have 3 WDS and 2 IDS units I just use what the dealer used from 1998 to 2009.
I don't know what else can read the Vehicle Setup and Configuration.

This thread is a few years old but since I started it I guess I will add to it anyway.

My “hard starts when cold” problems continue. I have discovered a way to make it better although its not what you call a fix.

If I park my car facing downhill it almost always starts instantly even if its been sitting for a week. If I park the car facing uphill and let it sit for an hour or more is is really difficult to start. Key off and on several times, lots of cranking until it fires. Parked level it may or may not start right away.

The spot in the driveway where my XKR sits is sloped, so I can back it in every day so it is is facing downhill, then it starts right up the next day.

Any further developments on their issue since 2019? Any repair found that avoids dropping the tank or chopping the car to replacing a perfectly good fuel pump? Thanks

 

Hi funracer,

I haven't tried to install a check valve in an X100 or X103, but it should be possible if a suitable point in flexible hose can be found. I've installed a few valves from McMaster-Carr (mcmaster.com) in XJ40s as shown at the link below:

Fuel Check Valve Installation XJ40

One thought is that McMaster-Carr sells many types of adapters that fit the check valves - it might be possible to find adapters that could be plumbed at the outlet of the fuel filter.

Cheers,

Don
