My 2001 BMW will not start. We put a new alternator on and we put it back together then when we try to start it it locks us out. We can hear the fluids running. We try to turn the online on but it kicks it back to accessories position and we have to turn it completely off.

VIN is WBAFB33511LH12109.
It is a 2001 BMW X5 4.4i.We where driving and all of a sudden it would not go over 20 MPH.We looked up issues for what we were experexing. We got it home and it automatically just died. We replaced the alternator. And we went to start it last night and you take the key all the way to start the engine and you can hear the fluids moving in the engine but the anti-theft turns the key back to the on position and will not let the engine start at all.We have been fixing things ourself but we are stumped here and don't know what to do.

If anti theft is on You will need a Capable Factory scanner or equivalent to Read the Fault codes in the Anti theft Module

needed here ,that is done by hooking up the scanner to your vehicle DLC data port connector and based on these faults we can pull up a Pin Point Troubleshoot and be Accurate ,If you do get the Faults Read ,Please post them back here for me and I can Help You Further on it and send you the pin point troubleshoot to perform or the most possible causes for it .

​you have door,hood,trunk, locks,ews module ,key , key rf signal coil rimg (common) to many parts involved to guess at it

no call necessary here ,will cost more money and not needed

We can check the 3 fuses ,for system, CLICK ON LINK TO VIEW IMMBOLIZER WIRING CIRCUIT I HAVE HIGH;ITED FUSES IN YELLOW FOR YOU

YOU CAN ALSE TRY MASTER RESET IN CASE IT WAS A GLITCH

Master Reset

1-Disconnect Both Battery Cables ,Positive & Negative .

2- Touch Cables With Each Other For 60 Secs ( this will take any residual power in the Harness to Reset the Vehicle Modules )

3- Wait 30 min

4- Close all doors and trunk

5- Reconnect Battery Positive First

6- Use The Key in The Driver Side Door

Lock Cylinder to Lock it & Unlock,IF You have only a Key Fob ,use it to lock and unlock

7- Enter vehicle and Start it .

​IF THAT DOES NOT WORKED HAVE IT SCANNED SO YOU ARE NOT GUSSING AND THROWING PARTS AT IT

a low or wear 12 volt car battery will trigger anti theft
