Greetings, Here is a good one for you, good test of your technical level of knowledge of BMW (what appears to be) an electrical problems. Here goes (step-by-step) of what happened: CAR: BMW year 2000 323si
1. Drove to the mall everything seems okay
2. Parked Car went into the mall 30 min.
3. Got back into the Car put keys in and started it (what happened?) the car for a very brief second attempted to start (very brief second). Next wont start, nothing worked at all, nothing, no dash lights, no electrical power as if the battery was suddenly removed.
4. called help AAA, suspected battery, fast charge and jump start ...car started no problem.
5. Now, immediately after start-up by battery jump, radio indicates disabled on the display (won’t work), seat belt light won’t turn off, and flasher for turn signal doesn’t work (turn signals work but without dashboard blinking, no blinking sound).

you need to check battery supply most important. if the battery low voltage, cause no start. if the battery ok & strong energy. maybe the drive away protection control if this is the problem you need to bring to BMW dealer to replace control & ENCODE the control unit using SSS.

Welcome to the world of BMW's. return the car to the seller. you got a bad one. You got an electrical short draining the battery. Bring a blank check and sign it over to the dealer. They're going to have to run through the entire electrical system to find the short. That work alone is worth more than the a used up 2001 325i.

If it does turn over and electrical works, then the problem is unlikely the battery. You can try jump starting. If it cranks when jump-starting it may be a weak battery, starter motor or alternator, but I don't think that this is the problem.
Check if there is spark on all cylinders. Do a code scanning (this car is OBD1, you will need to do the scan at the dealer place or to find a BMW OBD1 tool- Universal OBD2 scanner will not work on a 1994 BMW). If the codes return misfire or mixture related errors check fuel pressure, check sensors and parts that determine the mixture (MAF/MAP, AIT, O2 sensors, IAC and EGR system), check the vacuum system for leaks and check the crank sensor.
