Where is the ELD (Electronic Load Detector) on CRX????????

 

I think its in the fuse box, some cars dont have it. Did you just do a swap or change ECU's?

 

D16Z6 SOHC VTEC swap
OBD1 ECU

The engine swap itself was already done almost a year prior to this particular issue.

And I just finally recently swapped ECU to convert to OBD1 but this issue was already happening before the ECU swap.

I've had an issue I've been trying to figure out here.

So, today I was checking all connections while the engine was running. Pulled #1 wire, sputtered a bit, plugged it back in, and it idles smoothe again.

Pulled plug #2 wire, it bucked and died, plugged it back in, went to start the car, and get nothing. Turns over fine, but does not start up at all. Just floods.

I've done this (pulled plug wires) hundreds of times and never had an issue.

My CEL didn't come on, but I thought for ***** and grins I'd see if it would throw a code, so I jumped the jumper, turned on the key, and yup! Code 20! (ELD)

Help?

 

Nevermind, I figured out the issue. Well, at least I figured out why the car won't start.

After swapping out fuse boxes with a spare one here after thinking maybe the ELD was in that, it still wouldn't fire up, so then I figured out that something it up with the dizzy, because when I swapped it out with a spare dizzy here, it fired right up.

But still, where is the ELD on a CRX?

 

I believe the ELD on the CRX is inside the alternator. On my previous car (96 civic hatch) it was in the engine fuse box.
I have no idea what the problem may be.

 

I might also mention that after resetting the ECU, the code 20 went away.

But I still wanna know where the darned ELD is located on a CRX...

Maybe you're right audrey320, but who really knows?

 

as far as i know there isnt one on the usdm cars

or so ive read anyweay

 

Ok, got it figured it out, thanks to a fellew COC member, and she's hella smart when it comes to findin' that stuff out fast!

It is located inside the main fuse box (under the hood) on a CRX (usdm models included)... Question answered. Thanks guys.

 

When you unplugged the spark plug wire you grounded them right? If you just pulled them off and let them arc, you will destroy the ignition module. The voltage will go backwards to the ignitor if it doesnt have a ground. So that could be why it didnt start again.

good info...good post


its nice t see someone who didnt flame him for not grounding the wire but instead informed him...

What? I have left the plugs un-grounded and turned the engine over for like 10 minutes once (not continuously), the ignitor never died.

The voltage will go backwards? Do you mean the current will reverse in the primary side of the ignition coil? Or did you mean to say the voltage will reverse polarity?

I'm not a electrical engineer, but I do know that on an old point and breaker ignition systems the current in the primary side of the coil will reverse. So how would it do any damage to the ignior if the current already reverses? Second, I'm willing to bet that if this were a concern that Honda/NEC/Nippendenso would have simply integrated a diode in the ignitor circuit.


Someone please explan this to me?

Thank you for that point...

And it's true, I didnt know, simply for the following...

Good question. Now I wonder too, simply for the fact that I've pulled spark plugs thousands of times on a Honda engine, including this one, and have had nothing "drastic" happen before like this...

I'm confused...

 

red/grn wire in fuse box

 

Thanks Ryan! but I figured it out back on the 15th.
