When you turn the key there's no CEL... what about battery & oil warning lamps?
If NOTHING, then it's beginning to sound like a flaky ignition switch.

 

Yes.. battery and seat belt, and oil light are there and on, when it dies... i turn key back, and then forward to restart and the cel comes on then, along with the other three. I made a video for it in my last post, thread "90 accord ECU help".

I hope its not the ignition switch.. I dont wanna see the inside of a junkyard again.

Is there any relation from radio to ecu? When I go the car the radio was gone, wires all over, someone hooked up an after market.. but took it when they left the car... I see the radio/backup fuse has something to do with the ecu resetting..? I installed a new factory radio out from the yard, and its acting weird.. turns on.. but cuts of randomly...

Im on my way out to it now.. to start it up, see how long I can keep it running... when it cuts, im gonna check for codes again.. and If nothing Im gonna pull the main relay and check for busted soders.

Once again I appreciate all the help guys.. I cannot wait to pimp this accord all over town!

 

Not much in common between radio & ECU. Only share the backup power to maintain their memory when the car's turned off.

Radio is powered by accessory circuit through the ignition switch.
ECU is powered by main relay which is switched on by ignition circuit thru switch.

If it were a bad ignition switch, the oil & alternator lamps would go out too.

 

Ok.. thanks for info this may help... my radio power wire has burnt/fried completely through the main wire harness... its burnt behind radio, and burnt under dash, so ill guess its burnt all the way to ignition switch. Prolly burning any wires near it... I need to find where/whatever the power source is to radio power wire and clip it off completely. Don't want power running through a bare wire... in middle of harness...

My main relay has been manually grounded, someone sliced the ground, and added another ground to it... somehow the main relay ground is no longer working... Need to find the source of that problem...

 

Yeah, I saw that in your other thread after posting this one. Someone already said it, but with butchered wiring like that your problem could be almost anywhere.

I was gonna say you've got like 3 different threads going, so it's confusing. At least to me. I read one of the threads & doesn't dawn on me right away that you're the same guy from the other thread. But then one single thread would be 8-pages long... ya can't win.

 

Yea, lol the problem is 21 yo car that nobody took care of... im enjoying trying to fix it, and when its done, ill love it even more.

If I have to pull a wire harness, out of a junkyard, I will... Ive spotted 2 or 3 nice cars already.

Ill start with this radio wire, here in 10 mins... pop ignition, trace wire to it, and clip it. Dont want it sending power through that wire anymore...

Yea im in a couple threads, with similar issues, trying to figuire it out. Yall have been great though I must say!

I hope to post some good news later, like SHES FIXED! haha Maybe Ill win a small victory with my lil beater..!

 

fixed ground issue... and steroe is disconected with no fuse in, no power thru busted wire...

CEL is blinking again, and it gave me a code 15 again... Ive already done coil, cap and rotor... need a voltmeter now to test voltage, and that would point to...? the ignition switch? or ignition control module, the other thing in distributor?

 

Code 15 is "ignition output signal" meaning the signal from the ECU telling the ignitor to fire the coil. Often that's either open wiring from ECU out to distributor, or a bad ignitor. Sometimes AutoZone-type places can test Honda ignitors.

 

Low and behold, the blue bandit is ON THE ROAD!! I got a scrap yard ICM, screwed her in... and she is workin great fellas!!

THANKS to all you guys for the help!

I just test drove for over an hour, like 40 miles, and she is runnin strong. Confidence is back jack!!! yet she is 21 years old, im sure ill be back haha
