ECU keep on beeping when the ignition is on and while I'm driving. If any one know why, please let me know.

The car is a 90 hf with a 89 CRX SI ECU and fuel injectors.

Thanks.

 

do you still have the hf ecu? if you do put it in and see if it goes away...

 

Thanks for the post back but when i did have my HF ECU in, my car wasn't running right. It run like my fuel injector is clogged or not firing correctly.

 

did you still have the si injectors in?

 

Yes cause thats the only way the ECU will read my injector right cause it won't read the HF right.

This never happen before when I have the SI ECU, injector, and tranny on the hf motor but when i rear ended a car, I swtich every this over to my other 90 CRX HF. I put the HF tranny back the motor and the HF injector and ECU, but my car wasn't running right. It feel like its miss firing or the inlector is clogged.

thanks for the post back

 

ECU is beeping?
ECU's don't beep!

Do you mean that it keeps triggering the CEL?
What code(s) is/are you getting?

 

Um the injectors are the same and it is prolly beeping cause the door isn't closed all the way or something. - poke.

 

i'll check whats the code is.

Thanks for the post back.

 

plus the CEL is not ON.

 

I'm pretty sure that its not my door cause if my door isn't close all the way, my door light would of come on.

thanks for the post back

You lucky bastard, no matter what position my door is, the light wont give a ****. Plus the sensor is all loose.

 

Maybe its an ICU???

I dunno if the CRXs had them but in my 91 integra we have an ICU that controls things like the windshield wipers and a couple other functions...one of them is the door or key-in-ignition beeper.

 

Now my ECU not beepimg when I'm driving but its only beeping when the ignition is on the ON position. I don't know why its doing it but I want to get rid of the beeping.

thanks

 

thabks for the reply back but i don't know if i have an ICU. I'll check but I'm not sure.

thanks anywase

 

damn that sucks. I would of went crazy already if any lights would of stay on any where in my car. well good luck with your door.

thanks for the post back
