Hello

I had a very similar problem with my 1997 406 2,1 TD

When started from cold, the car would drive as a horse, which needed to be broken in! After a while, when the engine was hot, the problem disappeared. It would be back at the next cold start. Sometimes it happened even when the engine was hot, but that was seldom. As the car is quite powerful, it is quite a scary experience.

As you mention in one of your answers, the fuel system on these cars is rather advanced. You have one solenoid for accelerating, one for decelerating and one transmitter for telling the computer the position of the speeding system between idling and full speed. Furthermore there is one adjusting device, which handles the ignition timing and a transmitter telling the computer what the timing actually is. The last electric thing on the pump, is the stop solenoid.

On my pump it was the transmitter telling the computer about the actual timing position, which was faulty. When you go to the garage tell them that. Otherwise they will very likely try to sell you a complete new pump, which will obviously solve your problem, but at presumably at least 10 times the costs. The transmitter would cost in the region of 120 to 140 pounds as it is 1500 danish kroner here in Denmark. The item is quite small maybe 3*3*4 centimetres. It is a Lucas part (as the rest of the pump). The numbers with which it is marked with are:

9160-012-A 4495 0496 (forget about the 0496. I think this is the production date) Made in the UK

It is placed on the side of the pump which is nearest the windscreen. It is the only electrical thing on that side of the pump. In my case I was not sure that a new item would solve the problem, as I had to figure it out myself, so I bought a used pump, and just used only the part in question. Finding a good used pump is however tricky, as it might very well have he same fault. The best thing would be to arrange with a garage to exchange the transmitter. Depending on the garage you might get a deal where they take the item out again, and give you some of your your money back, if it does not help. 140 Pounds is quite a lot of money, but the alternative is not that promising either! This fault is not easily found/verified on the OBD garage computers (at least not the one I tried), so don't be fooled by that.

Good luck with the project. Please let me know if it helped!

Best regards V6406 Denmark

I still think the feeler on the pump is your problem, but the link might interest you anyway.
