Sorry this is in english. Can you help?
I have Electronic injection and it was going into garage for work on tuesday as it doesnt start very well I have to prime the pump 8-10times to get it to start.
Today though it started as normal after a couple of attempts and I revved a little and it just cut off when I tried to start again there was no pump sound and no relay click.
I have 3 relays next to the battery what is each of them for? all the wiring is in black? with different colour connectors.
After a bit of “tinkering” it started then I touch the throttle and it did it again?
Now nothing…

revision

I have found out what each relay does and colour codes from a WS Manual I am getting
NO Click or Pump noise any ideas? Is there a fuse somewhere?

please type car, year ? do you have a stratbutton on the battery ?

1972 DS21 IE Pallas
Yes i do have a start button on the battery terminal

are the injectors getting enough power?

I do not know. When it was running it was “lumpy” when cold but got better and started badly from cold or even after 3/4hrs of being left. I had to keep turning the key on and off about 10times to prime the fuel.
Now if I turn the ignition on the lights come on but the relays do not work neither does the pump “buzz”

one of the relais near the battery is turning the fuelpomp on so….....
if the relais dont work then the fuelpomp cant work
the relais for the fuelpomp is turnt on by the ECU.

but in that case, the car wouldn’t run at all in stead of now running ‘lumpy’
unless the relais does work only now and again, which I seriously doubt

maybay the wire to the relais of the fuelpomp broke….........

by now it looks it could be all sorts. from broken relais, broken wires to even maybe the ignitionswitch. time to start measuring the different things to block all different failures out.
anybody in your neighbourhood who is capable? i think we are slightly too far away for this.

Well theres a funny thing!!
A friend came round and I was moaning about the days events I turned the ignition key to “show him” and it worked and started?? ops:
It works again… as long as it gets me to the garage I had booked it in for on tuesday. I did spend a while cleaning terminals and I renewed the earth to chassis wire afterwards.
I dont like the starter switch next to the battery either although it may be handy for cranking over.. there is no back cover on it either so metal terminals are showing   add it to the list…
Thank you all for your help. I will definately come and see you in the creuse when the car is back….
