Default 95 civic -- Is it my ECU or ICM ?? -- Solid CEL

My civic just died going down the road. It has no spark but CEL comes on for 2 sec. and goes off when key is turned on. I've tested main relay and it's good. I smell fuel at the exhaust and hear the fuel pump running during the 2 sec period after turning the key on.

I've used the following instructions to check my coil and ICM:

********
On models with single-coil ignition systems, if the
engine cranks but there is no spark at the plugs, check the
ignition coil and the ICM (ignition control module
[igniter]) by using this procedure:
NOTE: Wire colors for wires referenced here can vary
between models, so use the appropriate ETM to ID them.
1. Turn the ignition switch ON (II), and watch the MIL
(malfunction indicator lamp).
If the MIL doesn't come on, or it comes on and
stays on, refer to MIL Basics on this page.
If the MIL comes on for two seconds and then goes
off, go to step 2.
2. Check for battery voltage at the positive wire going
to the coil, and at the positive wire going to the ICM.
If you have battery voltage, go to step 3.
If you don't have battery voltage, check for an
open between the ignition switch, the ICM, and the
coil.
3. Connect a voltmeter between the coil negative terminal
and ground, and record the cranking voltage two ways:
first with the wire between the coil and ICM connected,
then with it disconnected.
If you get about 8 V with the wire connected and
10 V with it disconnected, install a new coil, and
retest.
If you get about 10 V with the wire connected and
disconnected, install a new ICM, and retest.
*********
I get through step 3 and get around 10v (connected and disconnected). I have been told because my CEL is solid (jumpered 2 pin connector @ ECU) that my ECU is bad.
One other clue is that there was a small amount of oil in the distributor cap....like the internal seal is leaking. There may have been enough to short the ICM. There were no blown fuses.

Any help greatly appreciated.
thanks,
mike
