The Bentley manual carries the wiring diagrams for the E36 vehicles.

this could be due to a defective alarm sensor unit.

e36 m3 cab flat battery.i have now fitted a new 1 and my alarm will not work and the car is immobilised.the key fob is black with 1 button in the centre and the car is a 1995 can you help.

Hi i have just put the rear bar anf front bar form a e36 convert on my saloon that i got from the scrap yard the other week and they fit fine for me..... i hope this helps you.

You car should have a harnas already installed. Sigma and stellar alarms are easy to fit according to pro's. visit bmw e36 blog for more details.

check fuse?
relay of fuel pump?(in the separate box beside the fuse box?
is the current on fuel pump?under seat in back,right side,take of cover,black,find connector with biggest wiring,other with fine cable is fuel meter,
with back seat away and cover open,when starting,no doupt,you should hear the pump,
if all ok,
check ignition coils,but,it would seem bizarre they all four brake down in one shot,
fuse box,check power,
and....also check relay under stering wheel,is fo alarm,but...aso happens....
good luck...
