Peugeot 306 Bj. 97 75PS 1.4L

Good evening, I’m new to this forum and have a few questions about my car problem. My car: Peugeot 306 75 hp (55 kW) 1.360 cm3 Petrol HSN/TSN: 3003/818 Now to my problem… First, the car no longer starts, because there seems to be a defect in the spreader or in any cable. If I only make the ignition (not start) then you hear the double relay going on and off again and again, so it always clicks. (not fast but rather so all of them) I tried to separate the petrol pump from the system and simply took the plug off the back. But the problem was still… My display (km/H) is still moving, so it’s a kind of twitch but not in the clock, only occasionally and irregularly. (even if I jam off the petrol pump!) I also have the problem that it doesn’t generate a spark on all spark plugs when starting. (have all tested individually.) t by keeping it to the ground) What I’ve already done about it… Double relay behind the control unit replaced (newly purchased) Almost all cables controlled (visibility test) All fuses checked (also in the engine area) the crash switch controlled (everything in order) battery replaced voltage tested on the plug of the petrol pump at the rear (starts with the clock on and off) More info Everything in the cab works, i.e. window lifter, radio, ventilation/heating, ect. pp. (only the display km) /H spins) Light/remote light goes also warning flasher goes also braking light goes also It also shows the “motor control” light, I guess is due to the problem… Now I have bought a new/use-test control unit to see if it could be because of it. If I can’t solve the problem with it, I wanted to ask now what to do or vlt. does someone know the problem and can help me with it?? I would like to thank you very much in advance, for all e Tips and suggestions for solutions!
