Already checked. In both filters, the gasoline are clean as well as in the fuel rail.

Just follow the advice of the experts here on the forum and you will be back on the road in no time. Can you tell us where you found this car? Is it unusually for junk yards in your area to have cars like this or did it just come in and you got it before they cut it up for scrap? You are a very lucky bloke!
I just went to the craiglist and find an advertisement for the sale of a jaguar in Sacramento, my friends live nearby and an hour later they were already watching the car. Friends said that a very good condition, the next morning I bought the car)
The former owner sold the car to the junkyard just two weeks ago) several people approached me and were very surprised that the car was in such a condition at the junkyard. They even envied that they didn’t see this jaguar before me)

Don't forget to test and possibly replace the inertia switch. My car was acting up in a similar fashion and I replaced it with a series 3 unit. ( I have a 78' series 2)
This a common problem with these cars apparently.

Just a thought.

I still can't believe that car came out of a scrap yard !! It is a real beauty.
You might find this of interest: -
Fuel injection and the Jaguar XJ6 4.2 Series 3 / AJ6 Engineering
Pay particular attention to the known fault within the AFM of the two very small contacts that maintain voltage to the fuel pump relay. Your car seems to have the same symptoms I had on mine, namely a sudden and unannounced shutdown of the engine, (and in very embarrassing situations too,like poo on the seat stuff when overtaking !!)

It's San Francisco, Jim, they throw away some of the Most Incredibly neat things!
I agree though, this is the Nicest car I've ever seen in a junk yard, even just out the door that they hope to sell to some unsuspecting sucker. Good Score!!

I'm not sure how unplugging it would help the stalling issue.. Maybe it was stuck open and you had a constant flow of fuel into the intake? Perhaps you were overfueling??
I hope it's the issue..

Another thought about the fuel pump...
I had one that would read a perfect 34-36 psi at the rail at idle...
When it was under load it would drop way down, eventually stalling out the car.
The way I figured it out was to run a long fuel line from the fuel rail (where the cold start injector line is) to the windscreen, with a pressure regulator where I could see it going down the road. Replacing the fuel pump solved that issue... may be something to check out...

That sensor is called the Thermotime switch. It is part of the cold starting system, and controls the feed to the cold start injector..

0280130220 this part number.
Are there analogues? or just the original?

Full disclosure, this is my site, but here is a link...
https://shop.everydayxj.com/XJ6_Ther...13-eac1385.htm
If you pull it out to test, you should be some resistance (seems like 50 ohms or so, I think) between one of the pins and the bottom of the switch, and also between the two pins. On the other pin and the bottom of the switch you'll have an open circuit... When the sensor is cool..
Those values will change when the sensor heats up...
But, if it's calling for full time spray from the cold start injector, it's just as easy to confirm that being the running problem by blocking off the fuel line to the cold start injector....
It's just tough to figure out how that could be an intermittent running problem, that would go away with a stop and restart....

"I replaced this sensor, started the engine. The engine worked for an hour. I drove about 10 miles to work, stopped the engine. After 20 minutes the engine will not start again until it cools"
Have you ever lifted the fuel caps and check to make sure fuel is being returned to the proper tanks?
Thinking you may have a bad return valve going to one or both of the tanks...
Thought of grabbing one of the ignition amplifiers from one of those parts cars? That may help, too.....
