    Hello, my friend did me a major overhaul of the engine after putting it in, I can not start it on Plaku. I will add that the fuel does not give the injections, but comes to the pump and returns. I also have a diagram where and what the relay should be, maybe someone has a diagram with fuses and relays for the t4 2.5 diesel 2002 (because after the purchase there was no relay and fuse) I bought it for heating candles and for the fuel pump, but the pump does not fit anywhere Can someone advise what is wrong with him? (I will add that there is no front belt) What may be the reason that I do not want to start. The pump and injectors were handed over to a specialist.
