All electrical systems work but starter will not engage when key is turn. There is nothing. Dead silence. By passed starter and solenoid works fine. All electrical loads working fine. Car belongs to a friend, just bought it last week. We think it has something to do with Anti Theft system. Car ran great, he pulled in for gas, shut it off and could not start it agian. Has new battery, starter checks out, fuses fine. Will the "stomp test" reveal an error code for this?

Procedure for acquiring error codes from Bosch Motronic DME - aka "Stomp Test"
BMW e30 s, which are 1988 and newer, have Bosch Motronic versions M1.1, M1.3 and M.7 and can display fault diagnostic codes. Procedure for obtaining codes is:
■For safety reasons, put the transmission in neutral, and turn the ignition key to "On" position but do not start the car
■In quick succession fully depress and release accelerator pedal 5 (five) times
■After couple of seconds Check Engine light will blink once, and start to flash code(s)
■All codes are composed of 4 digits (see table below). For example, code 1211 is represented as Blink, pause, Blink Blink, pause, Blink, pause, Blink
■When code(s) start to repeat, all of them have been displayed

Call or write back if you have any ideas. It has to be this or the DME.
