Dream becoming a nightmare

[Den Maggs]

I am so hoping a member on here has the answer !!! I acquired from family member a 530d SE 2004 , which he delivered to me (driving it) told me there was issue with battery and need replacing - which I did and the car won’t start , investigation led me to the IBS lead and negative terminal , replaced it , still nothing !!! Puzzled , noticed when connected battery and attempts to start , the fuel pump was silent , and a fuel pump warning message displayed , so decided to replace it , again it started !!! Yes !!! I drove it around the block for 5 minutes returning to my road , when all of a sudden it died !!!! Pushed car back , researches and finds a 20 (yellow) had blown , replaced - blew - replaced - blew , research again found that the fuel pump relay could be the issue , so replaced that , again started the car , nothing !!! Cranks away !! Fuel pump warning message has gone , unplugged the IBS tried again , nothing , I am totally at a loss as to the issue as every bit of research has lead to everything I have done or attempted to !!! Any ideas what I should do or what I have done wrong
all replies are greatly appreciated

If the battery is new to the car it should be registerd.
If that is not the case, you could do that first to sort out the problem with your IBS.
Otherwise get your car checked with ISTA and read the fault codes.
If a 20A Fuse pops everytime then there is an open or wet cable I guess
