I know y'all sick of me by now lmao but I'm trying to get this car right. It's a 2012 Jaguar XJL Portfolio 5.0; I just programmed my 2 keys to it last night. Issue I'm facing now is the car is running but is misfiring all all cylinders and it gives off a very strong gas odor. Just a back story; I bought the car from a Police Impound Auction and it was sitting for little while before I bought it. Vehicle history looks clean and I was told it previously ran but guy was arrested and all vehicles were impounded. I also want to add I gutted the inside of the car and a lot of the electronics aren't currently installed except what I felt was important ie Cluster and radio


Codes that came through on JLR SDD

P001D-13 Intake (A) camshaft profile control circuit/open - Bank 2
P0660-13 Intake Manifold tuning valve control - circuit open - bank 1
P0087-00 Fuel rail/system pressure - too low
P0313-00 Misfire Detected with low Fuel

 

I don't see any misfire codes for individual cylinders - is rough running what has led you to believe it is misfiring on all cylinders?

Given the strong gasoline smell and the P0087 code, you may have a fuel leak that you need to locate and rectify as soon as possible. You may also have some electrical issues. The DTC Summaries at the link below give the definitions and possible causes of your codes:

Its misfiring all cylinders. I have these codes as well

codes:
P0300-00
P0301-00
P0302-00
P0303-00
P0304-00
P0305-00
P0306-00
P0307-00
P0308-00
P0316-00

 

Aha! Well, please don't give us only part of the information! Are there any other codes stored?

Low fuel pressure will definitely cause misfires in all cylinders.

 

The low fuel pressure can be caused by 3 things: 1) bad fuel pressure sensor, 2) bad high pressure fuel pump(s), or 3) a failed open fuel injector. So, you will need to do some investigation. If you have pulled apart the high pressure fuel rail, I would bet you got something into one of the fuel injectors. If this is the case, I would remove all 8 injectors and do a cleaning. This will then tell you if have a bad injector. If so, replace. Also, make sure to note what hole each injector dame out of as they are matched to the cylinder.
if that does not fix it, the replace the sensor (cheaper and easier of the 2 options). If that does not fix it, then you will need to replace both fuel pumps.

 

Low fuel pressure can also be caused by a leak in the fuel lines, little or no fuel in the tank, a clogged fuel filter, a crimped fuel line, etc.

Fuel-related misfires can be caused by fuel contaminated by water, which is surprisingly common.

Here are the definitions and published possible causes of the codes we know of so far (not including the cylinder misfire codes). The strong fuel odor and definition of P0087 are what prompted me to suggest that a fuel leak be ruled out. The P001D-13 and P0313-00 DTCs also suggest a problem with a cam solenoid or sensor or their wiring.







Before we try to help much more, are there any other codes stored? It helps to see the complete picture.

Cheers,

Don

It wasn't part of the information. The longer I let the car run the more codes that are coming in. Theres 100s of codes but these are the only ones from the PCM. the rest are for BCM, HVAC, Lights, etc... Like mentioned everything inside has been removed.

I have taken anything off the engine only gutted the interior.

I don't see any signs of a fuel leak visually and I only smell gas from the exhaust when its running like it's running rich. Fuel is low and what came in the car when i got it. I haven't added any fuel. Lines also don't look pinched or crimped.

 

That could be consistent with Chris' suggestion of leaking fuel injectors. The fuel in the tank may very well be contaminated with water condensation or simply past its prime. It might be worth adding a couple of gallons of fresh premium gasoline with a good fuel injector cleaner like Techron Concentrate Plus and allowing the engine to run for awhile to see if injector performance improves.

 

I did a full look over the car and can verify no leaks found and wires except the throttle body look good. Smell is coming from exhaust. Even crazier when you cut the car the car off liquid gas literally comes out the exhaust. At this point I know for a fact I need to do a oil change as that much gas not burning is definitely getting pass the piston rings. I'll try some fresh gas and Fuel treatment and see how that goes.

 

Definitely sounds like a sticking injector.
Have you tried pulling the plugs on each cylinder & looking for one that has wet spark plug tip and/or wet gas in the cylinder? A boroscope really comes in handy to look into the cylinders for which one looks like it's getting too much gas.
On top of that ruining the oil, it'll also damage a catalytic converter.

 

I haven't done that yet. I was gone to try fresh gas and Techron first and if that failed start pulling things 1 by 1

 

I guess I am confused on what your doing?
Why did you strip out the interior of the car? Of course that will cause hundreds of codes. Why would it not? Nothing is hooked up anymore.

Car got alot of water in it from the cabin filter and I mean a lot of water. So I pulled everything to suck the water up and replace the carpet. No mater how much I shop vac the carpet; there was still water in it. I also removed the dash as I got a replacement due to it peeling and cracking.

 

Durvelle27, the conditions that you are describing are almost spot on to what I had when my car suffered a failed fuel injector. This is why I am saying you can try replacing the pressure sensor and fuel pumps like I did, but ultimately I had to admit that the fuel injector(s) had failed. In my case, I had a potential reason as I had a shop that had just done a lot of coolant work and they removed the intake which caused them to have to break the high pressure fuel lines. So, I suspect that something got into the system that way. In your case, it may be that because the car has not been run in some time, gas dried inside the injector and it is causing it to stick and not perform correctly. I know you are not looking forward to pulling the fuel injectors, but from what I have seen here, the fuel injectors are the more likely culprit of what you are seeing.

 

Alright I know it’s been a few days but here’s an update. I’m actually no longer thinking this issue is clogged injectors or sticking injectors. I’m starting to think it’s electrical related. I drove the car and the battery light kept coming on and it drove worse and worse. Battery is a brand new AGM battery and alternator.

ripped all the carpet out and this is what I found on the passenger side under the seat







I also found this under the passenger seat. Looks like a inline fuse that was installed between the ground from the rear to the front

 

Man that looks like a flood car?

Might want to consider replacing the body harness as a starting point. Have had to do that on an XJ with severe water damage. Once you get rust/corrosion in some of the electrical connectors, it ends up in all of them.

Is this a car you need to keep? I would bail on it and find one without water damage, as a technician.

 

Don’t get floods here. Was a dang leak that I still haven’t found. I thought it was the cabin filter but I fixed that. Now I’m thinking the sunroof or windshield

I was definitely looking to replace the interior harness. Only the passenger side is affected. Everything else is clean. Instead of replacing the entire harness I was thinking of cutting out all the corroded wires and splicing/soldering in new wires in the affected area and replacing the whole main ground as it’s corroded badly.

honestly I’m debating on it. These cars are super hard to find here where I live. I’ve literally never seen another I. Person outside of the donor I’m using to fix it.

 

I thought you just bought this at an insurance auction recently.
Whether or not you get floods locally doesn't matter; vehicles that are totaled in floods all over the country & beyond are shipped out of the areas & sent to auctions where people aren't as sensitive and aware of the risk of flooded vehicles at auctions.
We see car carrier tractor trailers hauling cars across the country regularly.
