Tested with a noid light. With a voltmeter i saw +12v to ground on one lead and +6.5v to ground on the other. Checked my S320, noid light worked and lead to ground that was +6.5v showed 0v on the S320.

Anybody care to comment?

depends on if the car is running or not. :D
If its not running then I would assume the crank position sensor has gone and that automatically switches off the injectors if the ecm doesnt see a signal in 3 rotations of the crank.
if it is running then you are probably doing something wrong or could sell it to barnum and bailys to go next to the bearded lady!
more info please :confused:

Found this on the internet a few minutes ago. Definitely my problem. Didn't know I had DAS. Now gonna try to figure out why it tripped with my only key...

On vehicles starting model year 1996 (HHT Diagnosis Version 46), the
RCL system is enhanced with a so-called drive authorization system,
stage 2 (DAS).
The activation of the drive authorization system (DAS) is initiated by
the RCL control module and transmitted to the engine control module
via the CAN data bus.
After activation of the drive authorization system (DAS), the fuel
injection system is rendered inoperative by the engine control module.
The drive authorization system (DAS) can be activated or deactivated
with the infrared remote control transmitter or the master key.
The engine control module and RCL control module are permanently
locked with one another by an identification code. This identification
code can not be erased (see HHT actual values “DAS“ menu
selection 3/6).
