Car wont start after replacing fuel system
Hello,
I bought a x1 18d where the fuel system broke down after filling gasoline on it. From what the seller told me the only thing missing was replacing the injectors. SO I replaced the injectors and rail. He sounded legit and the HPFP seems new from what I can see. The car cranks, but wont start. Got following fault code: 4B90 Rail-pressure monitoring on engine start. Could the pump in the tank be faulty? Is it suppose to prime on ignition? Any ideas? Before connecting the injectors I filled a big glass of diesel coming from the HPFP and it looked good. Do I have to program the injectors? - Thanks! |
