'83 533i HELP *no start*



Hello all!
So I have a 5er that doesn't seem to want to start....

here are my symptoms...

- -*NO* ICV buzz when the key is turned to the ON position.
- -Crank, but no spark, obviously no start.

SO.  Thought occurs, the ICM (Idle control module) is located on the drivers' 
side of the dash.  Well, I tore apart that whole region when getting the 
pedals, clutch master, etc. out of the 533 to xfer to the 6er (b/c I did a 
tranny swap).  So, obviously I ended up disconnecting all the connectors 
going to the ICM, the "CODE" box, and the chime, along with the breaker for 
the windows, and the cabin temp. sensor.  So, I start looking around....

BINGO, a 2-pin connector that is connected in series with one of the pins 
going to the ICM is disconnected, so find the connecter right?  Nope... I 
can't find it anywhere, and while I run around trying to find the picture I 
took of all those connections, maybe you guys can help!

Bottom line, here's my hypothesis...

- -	I think that the ICM has something to do with the problem
- -	The ICV is not buzzing (which I'm pretty sure means the DME is saying 
"no-go" on something, The ICM?)
- -	It worked fine before the tranny swap
- -	The reference sensors SHOULD NOT cause the ICV to not buzz, but in 
case you are curious, I am using the SAME ref. sensors that were on the car 
to begin w/.
- -	The *$(&$(*# thing won't start!  I want it to!

So if you have any advice I would really appreciate.  I am no stranger to 
troubleshooting this SAME exact problem, but I did that on an '88 635 with 
Motronic 1.1, the 5er has Motronic 1.0, a couple changes.

ALSO, I found the ICM has what looks like a removable "memory chip" on it... 
anyone know what this does?  Thanks in advance for ALL OF YOU HELP!!!!
