Very Concerning, I clone these ECUs as part of my business, never heard of so many going so wrong. interesting enough I am visiting cyprus this year if you want me to give it a look over haha. I remember your HPFP was giving you a code for the quantity control valve, possible it is building up with sludge or algae, not too tough to take off and clean
@SprinterFix When a friend of mine (Mechanic) had a look at it and scanned it with his scanner, he told me that the injectors were not firing up. So I will be replacing the injector's drivers, all four of them on the old ECU (when they arrive) and see if the faulty ECU can start the engine.
@@yiannakosautomotivekeys2380 injector drivers? what are those? I am not familiar, if ecu is not firing injectors its usually either because of low crank rpms, low fuel pressure, or sync between crank and cam, I assume that qc valve code u mentioned a while back is causing low fuel pressure and thus ecu is not trying to fire injectors.
@@sprinterfix No no no. I soon as I changed the ECU everything worked, so non of what you mention is at fault. I measured the injector drivers in the ECU and I am not getting any readings on all four of them.
@@yiannakosautomotivekeys2380 ahhh I see, now that makes sense, I have done very little work on the ecu itself, they are tough to open haha and I am not good at soldering. I am looking forward to seeing a video of the ecu being soldered.
@@sprinterfix If you open e few ECUs then you can get the hung on opening them and then it becomes easier and easier. I'll show you when you come to Cyprus lol.
