Recently bought a used 2004 530i that the dealership said had a dying battery. The old battery was a DEKA 70 @ 900 CCA. Bought a Duralast AGM-H8 to replace it and after installing it, the car won't start. The lights and iDrive turn on but no start. Figured putting the old battery back in would at least get it to start (as it did before) but no cigar with that either.

Any ideas anyone? :dunno:

does it crank? Can you here the Fuel pump on?

You mostly likely will need to have a mechanic involved on this one. The reason is, once the battery is dead or replaced your computer needs to be reset.
Good Luck !
