Hello, I’m new here would like to introduce me briefly: Beyond the 40, trained car driver, but for 15 years only hobby screwdrivers technically but reasonably at the height of the time. I have Clio 2, 3004 147, which now somehow brings me to my limits. BJ 05, 1.2l 55kw, should be a D4F, control unit from Siemens, does not start, ignition spark is there, petrol pressure is on the rail. So petrol pump runs. If I then feed him with start pilot he comes, but goes out without pilot again . So the injection valves don’t open… . OT Geber already changed on suspicion, but should he not have been anyway, would not otherwise run with pilot either. Currently no fault in the memory. Otherwise nothing inconspicuous, plug all in their place, relays where possible sometimes exchanged among each other, fuses ok. Can someone tell me what the immobilizer turns off, starters, ignition, injection, or everything? Otherwise any ideas? Thanks already in advance!
