Do you have a SECURITY light that's on in the cluster.
Was this an "intermittent" before it became a nuisance? The first thoughts for nearly all NO CRANK is PASS-KEY. Do you have multiple keys? Is the car an A4 (AUTO) or an M6 (MANUAL)?
The portion of the CLUSTER you mention is dead is the SPEEDO/ODO ETC or the DIC right of the cluster? Did the CLUSTER issue happen prior to the NO CRANK? It might be considered odd to be related. Coincidental? Maybe not.
What have you done recently to the car? Any attempted repairs? Is the car new to you or you've owned for some time?
THEFT DETERRENT relay?

There's under-hood fuse blocks - does the OP need to go there "first"? Maybe NOT.
There's specific procedures for NO CRANK diagnostics and I don't believe I've ever seen removing the battery as being the "first" go to.

no security light on cluster
no symptons, just would not crank or start 2 weeks ago
yes tried differant key, checked the ohms on both and they was the same
it is a a4 auto
it is the center digital cluster (speedo, odom, codes etc)
the cluster went out the same time
i have owned it for about 9 years, never any issues, has about 97,000 miles
I have done this so far
new battery
jumped the starter, will only run a few secs ( i think fuel pump is shutting off )
checked the transmission range switch (console )
checked park plunger switch (console ) (placed resister on it matching key)
checked theft deterrent relay (center relay under console) power on the yellow, no power on the purple, can jump the yellow and purple bur will on run for a few seconds. i have 12 volt to ground power on the small yellow wire on the left and 12 volt to ground power on the small yellow with black strip.
i have checked all fuses

The "jump box" you mention I believe is only on '86 - '92 cars, you mention multiple fusible links and on later C4's including your '94 I believe there's only 2 and likely in the charging circuit.
There's under-hood fuse blocks - does the OP need to go there "first"? Maybe NOT.

OP - KEY ON do you get a full complement of the expected DIC lamps. Do they "time-out" as expected? Do you have a FSM by chance? FSM - Factory Service Manual
The ODO/MPH etc doesn't light when the HL/PL are on either? Maybe shine a bright light into the sensor on the DIC and see if that might change that. The LCD shows the CCM DTC when it's working but when not working ... If it were a FEDS I'd think you have SYS in the display and also the SECURITY light. Do you have a SES (Service Engine Soon)?
If the AC fuse is blown the CCM won't go into diagnostics - the CCM controls everything that you seem to have issues with.
It seems your CCM is actually ASLEEP and ain't seeing/reacting to the WAKE-UPS. Check that AC fuse, that's where the CCM gets IGN 3 voltage.
I didn't follow this .... ????
Post a snapshot of the "jump box" and the multiple fusible links that you mention on your '94.
The OP seems to have a pretty good idea of the "goings on" - just has a somewhat ODD set of circumstances it seems.

I am not tearing my car apart to take a pic for a book jockey. 
Maybe the poster will bless you with a pic if he goes in there to fix it.

Your thoughts are for a much later GM PassKey system.
Where did you get the "other/donor" CCM? A JY? eBay or ....? LOCAL buy from an individual?
Depending on the source there are a couple options.

See post HERE and THERE
An independent repair shop damaged my CCM computer when changing the heater core. After a 6 week wait GM shipped a remanufactured CCM and they installed it. The odometer reset itself to zero as part of this install. We didn't realize that we only had 100 miles to reprogram the CCM. Yesterday when I tried to have a GM dealer reprogram the CCM it rejected it and the CCM has to be replaced.

Yesterday when I tried to have a GM dealer reprogram the CCM it rejected it and the CCM has to be replaced.
The shop has a replecement CCM on order. My concern is driving the car while we wait for the CCM to show up. One "local expert" claims someone at GM USA told him that you only have around "15 starts" before the CCM disables the car and it won't start.
I have more than 15 starts on the car, it runs and the only difference is the interior lights go out a little quickly and the security light flashes a little longer, when you start the car, before going out. Other than that I have a 93 with 150 miles on the odometer.
Can anyone confirm or refute the claim that the car won't start at some point. I'm concerned about getting stuck if I drive it anywhere while waiting for the replacement CCM.
