Dear BMW community
I have recently had engine replaced in my BMW and mechanic has completed the swap he cant start the car. He changed the fuel pump, crank sensors and injectors etc but key issue he cant get it fix is that Fuel Pump is unable to push fuel into fuel rails and hence fuel cant get to injectors.
Car was parked for year and half and battery was replaced during that time. I wondering
- Could it be immobilizer which is not letting fuel pump to function or activate?
- Could it be fuel pump relay? Where is it located i can see if i can replace it.
- Why the current is not going to fuel pump?
Very unexpectedly i called an auto electrician locally and he refused to run diagnostic and said he cant touch a car with others worked on it, i was well disappointed as i was ready to pay :(, and someone should be able to help to find out what is wrong with it.
I really appreciate if anyone can please help me to investigate or trouble shoot.
Thanks in advance.
