Default ECU Codes?? for Gen2

Hi, I'm new here, I have a problem with my Integra.

I was trying to turn on the car a few days back, and I hear this weird blinking noise coming from below the dash of the passengers side.
I put my ear in the ECU's spot and the ECU is going BEEP BEEP BEEP BEEP BEEP BEEP ect.

The engine will crank, but it won't start, when I stop trying to crank it, thats when the ECU starts beeping. The Check Engine Light stays On.
The car won't start even if it's pushed.

What can I do?? Is the ECU broken?? Or is it just sending a code that something else is broken???
HELP!!!

I have a 1992 Acura Integra RS / 5 Speed.

Is the light blinking? If so, what is it doing, long blinks, short blinks, total number of blinks?

that's the problem,...
the ecu doesn't have any kind of light.
This is some info I got from http://www.g2ic.com/
-----------------------------------------------------------------------------------------------
ECU Codes.

Depending on which year your Teg is, there are two different ways to check your ECU code.

1990 and 1991 Tegs:
Your ECU is located under the carpet on the passenger side of the car. You have to pull back on the carpet to expose the ECU which is brass in color. There is a circular window on the face of it with red LED in it. This LED will blink and this is where you read your code.
To get the LED to blink, you must turn the car to the "ON" position but do not start it. The LED will blink with fast blinks and with slow blinks. If you have four fast and two slow, that is code 42.

1992 and 1993 Tegs:
Your ECU is located in the same spot as 90-91's but you won't be reading the code off the ECU. For you, you must jump a connector and then your Check Engine light will blink to tell you the code.
The connector you must jump is located under the glove box and should be green in color.

0 - ECU
1 - Oxygen Sensor
3 - MAP Sensor
5 - MAP Sensor
6 - Crank Angle
7 - Throttle Angle
8 - TDC Position
9 - No. 1 Cylinder Position
10 - Intake Air Temperature
12 - Exhaust Gas Recirculation (EGR) System
13 - Atmosphere Pressure
14 - Electronic Air Control
15 - Ignition Output Signal
16 - Fuel Injector
17 - Vehicle Speed Sensor
20 - Electronic Load Detector
22 - VTEC System Malfunction
23 - Knock Sensor
41 - O2 Sensor
43 - Fuel Supply System
45 - System Too Rich or Too Lean
48 - Primarry Heated O2 Sensor
54 - Crankshaft Speed Fluctuation Sensor
61 - Primary O2 Sensor Circuit
63 - Secondary O2 Sensor Circuit
67 - Catalyst System
70 - Automatic Transaxle
71-74 - Random Misfire
80 - Exhaust Gas Recirculation
86 - Engine Coolant Temperature Circuit
90 - Evaporative Emission Control System Leak Detected
91 - Fuel Tank Pressure Circuit
92 - Evaporative Emission Control System Insufficient

NOTE: Some trouble codes are not listed for certain models and some codes only apply to California cars.
------------------------------------------------------------------------------------------------

My ecu keeps beeping for ever.

Did you try resetting the ecu or checking the code through the connector?

I just don't get it....
How do I reset the ECU?? or how exactly I check the code through the connector???

"you must jump a connector and then your Check Engine light will blink to tell you the code.
The connector you must jump is located under the glove box and should be green in color."

Ok, so under the glove box I should look for a green colored wire?? And what do I do with that wire next???

I think it's supposed to be a green colored connector. You jump 2 posts in the connector with a piece of wire. To reset the ecu, look under the hood at the passenger side shock tower, there is a black plastic "box" that wraps around the top of it in the shape of a horseshoe. Open it up, the lid will tell you which fuse is for the ECU, pull it, and put it back in after a minute or 2. Try to get any codes before you do this, because they will be lost.

Thanks for the help,... I'll see what I can do.

I heard that checking the problems with a 'Scaner' or 'Dianostig Test' can only be done to 96' and up cars,... is it still possible to use a scaner on the earlier models??? someway somehow?
Thanks.

I really don't know, I just look at the light on my ecu and head straight for the Helm manual.
