I have a crx 90 , today i just try to started but doesnt wanted to , when i put in On Switch to try to see what code is it , the ECU light stay on forever hehehe ... im not a real mechanic .I think is the Main RELAY , but not sure. anyone wants help me , i will appreciate.

 

it means your ecu is toast...!!!

 

Have you recently done any work at all to the car before this problem? Even simple cleaning around wires is helpful info.

 

Try resetting the ecu first

 

Error code 0 (constant red LED) means the ECU's main CPU is not operating and the ecu is using it's backup processor. In this situation the car won't start very well and rev limit is lowered. It is not a wise idea to drive the car in this condition for any length of time.

main relay is the main culprit or damp in the ecu(in UK climate)

 

i didnt do anything just drive it hehe, but the wiring in the main relay its suckxxx i think some cables make contact ... ( black , yellow/black) looks like something happen ... lol

 

mmmyummm. butter or cream cheese on toast?

OP, your ECU is fried!

You can pull the 15A? HAZ fuse in the pass shock tower to reset and try again. PM6 ECUs are plentiful

 

i did it ... if u means take out the battery cables out wait 5 min and put it back ...

 

hehehe tomorrow i can test other ecu , lets see what happens , ... in the worst case if it still the problem probably fck up that one too ...

 

I dont where is it but i will take a look tomorrow morning .

 

i plug my pm6 in my friends car and works fine ...

 

clean your connections, bad ground??? try your friends ecu in ur caR?

 

was working on that , but started to rain , suckxxx.....

 

i plug my friends PG7 in my CRX same problem , CONSTANT LED...
also i was lookin cables and the black cables was making ground in the chassis , i know my wiring suckx ...

when i put the switch all cables are positive , less blue s/white , green s/black , black .... (they plug are 4 n 3 , the section of 3 cables are Ground)
is it normal ? Main Relay clicks just ones .Any suggestion ? hehehe ...

Thanks for all people tryin' to help me !
