Hi, the fuel filter is new and the fuel pressure is correcltly measured by the computer (because corectly reported true OBD). Take a look on the measurement. During this cession, I had a lot of issue. It can be observe a lot of oscillation on the measurement but the fuel pressure is remained stable....

Brian, it is what I thought and it is why I desasemble both pump and every thing looks ok. Same issue empty of full gaz. I made some measurements with OBD and measured the fuel pressure. It is stable whereas the engine does not work properly. I assume now that the fuel is not the issue. Need to work...

First, happy new year, I am working to solve my strange issue on my S (I confirmed that the fuel pump is not the issue because the fuel pressure reported by the OBD is stable, including when the engine operation is not correct). I need some help to find information about mode 06 reported by OBD. The...

All, I am back and I would like to point of view on my Lambda sensor mesurements from the OBD tool. 4 values have been collected. They are the 4 Lambda sensor data. The engine is cold, at iddle with some accel. I am surprise to see the lambda at the output of the engine goes in oscillation between 0...

personally, I think too much cars has been produced...... For me, a disel car shall be a french car, an English car shall have a prestigious engine.... I say that but 10 years ago I said that an english car is a car with a tractor engine and a chassis aged before the seconde war. Now, I have two Jag...

I worked a litlle bit on my S type in order to trouble shooting it. For memory, when I turn in right, the engine behavior is like a carburator one when the carburator tank is empty. When I stop tu turn, I need some few 100 meters in order to recover a normal situation. You can trust on french guy to...

Thanks Mike, I start to be desapointed with my S-type.... Really, I do not understand what happen. I used it again this week and when I turn on right it is like when you do not have fuel on carburator engine. you need to drive fews meters (some 100 to 1000m) before the engine works propelly and the ...

to remove the motor pump connector, push the small part of plastic and remove it. The reference of the fuel pump is YW4U-9H307-BA and the reference of teh motor is XW4U-9350-DA. I am desapointed because everything looks ok. I am not sure that the source of my issue is the fuel pump. When I turn on r...

I removed the part,
found the filter in the tank, the part was "ejected" from the pump.
The fuel pump was desassemblied.
next in the following...

All,
I have an ELM 237 interface and use the software "scan tool" that does not include many functions. for example no misfire or lambda reading.

I am intersted by your experience on software tool and why not for the Jaguar diagnostic......
Were can I found it?

Thanks for your feedback,
Richard

All, since now some months, I have an issue with my S-type V8 4.0. When I turn on right, I have misfire. I (finnaly) desassemblied the fuel pump and plan to buy a new one. The price in the official jaguar seller at Toulouse (france) is uncredible (close to 600euros!) whenthe price with SNG Barrat is...

globally same price for us....
Some years ago, I driven some very fast german cars (280Km/h....), now, it is time to drive safely a nice English car !!!!!

Hard driving?
you do not paid fuel in UK????

Well, I am back. I received finally my spark plug last week (they probably came directly from ajpan due to the delay!!!!). I found some time last saturday to rebuild some parts that will allow me to start the engine ....... No bad noise, no alarm reported by the car! I need now to re-assemble all th...

Fraser, I would like to say that the spark units have to access. the electrically one and electro-chemical one. I stay convinced that the apparent load seeing by the igniter is very important, from reliability point of view,for the electronic igniters that we have in our cars. I work hard to get the...
