Hello everyone.
This is a second time I am here looking for help and not contributing much which makes me feel bad but the issue is that I am still knew so either I don't know to help or someone way better then me gives much better answer..
I am giving my best but sometimes that just is not cutting it
Anyway its a bit of a long shot but maybe someone can help the issue is with Mercedes Vito 2007. Diesel the problem is with ECU, ill post pictures of ECU and board in the post.
Problem is that 3rd injector is not working and the ECU sends wrong signals at first but then stops sending signal at all, I know that since when i start the engine i can hear injector ticking but at much higher rate then the other ones and i know there is power coming to it. Injector, wiring and cylinder is 100% good and only ecu is left. I tested all diodes and fets on it and they all seem good. I replaced the IC that is circled in red on the picture but that did nothing. I am thinking there is something wrong with the current that is coming from injector but i am not 100% sure.
If someone have any idea what should I try that would be great!
Thank you all in advance!
Viljeri.
