H22A Swap, no spark.

[Raf99]

Hey,

I've been reading for about a week to try and figure out this problem.

I'm doing a h22a (JDM) swap into a 93 accord EX. I'm at the point of trying to start the engine but there is no spark on the plugs. They are brand new plugs, brand new engine/tranny and ECU. We replaced the coil with the one that came with the engine (believe the 93ex is external and h22a is internal). We did the wire splice as recommended by online and by the swap manual i ordered. The coil (positive and negative) is getting voltage, and no errors are thrown from the ECU.

We are about to try the old coil/dist, as we are running out of ideas. From days of reading I'm thinking its the distributor as the coil gets power. But is getting a new distributor my only option, is there a way to test the distributor?

This project is being worked on by myself and my mechanic. Only thing left to do is the power steering line, muffler...and little things (tranny shift cable bushings).

Any help is muchly appreciated. Thanks

(I look like a newbie on here with 3 posts, haha. But i've been reading on this page for more than a year, just never needed to post).

So far I think the best idea is to swap back to the old coil/dist. If this does not work then it would be a ECU/wire issue i think. He would have to check the "control wire" for the distributor as it may have power but the ECU is not telling it when to spark.

Any agree ?

Thanks in advance too.

if your 93 ex was extreanl coil then you should have just bought a h23a1 obd1 extrenal coil dizzy and plugged it right up.... its what i did on my 93 ex with a h22a4 swap

Are you sure your spliced the correct wires? There's 3 wires on the plug, splice together the 2 thickest wires.

Thanks accord2nr81, i'll look into this. If I can get one shipped quickly i'll grab it. Do you know any sites that have this for sale?

d112crzy - Yep, splice together the black/yellow wire with the yellow wire. (large wires).

I think for troubleshooting sake we'll try the old coil/dist. and see if it works. This will tell us if the ECU control wire is working. If so we'll put the new coil/dist. back on and troubleshoot it. I'll double check the wires too.

Thanks

it won't bolt up.

[accord2nr81]

h23a1 dizzy will bolt up to a h22 no problem..... its what i got on my car....

h23a1 dizzy will bolt up to a h22 no problem..... its what i got on my car....

No one here is talking about the h23 distributor.

He said he's going to try the old dizzy/coil. Old dizzy/coil=f22.

F22 distirbutor housing does not bolt up on an h22 head.

The internals will interchange however.

[Raf99]

Ya, i think the dizzy is out of the option anyways. I'll get this on the road quicker if I just solve the current issue.

It has to be the control wire coming from the ECU as the coil has volts (+/-).
We'll know as soon as we hookup the old coil/dist.

But thanks for your input guys. It helped!

whats the condition of the rotor and cap, not likely that it would cause no spark, just weak spark...unless the electrode on the rotor is bad.....posibled not likely....yeh make sure ur splice is well connected, and at that point the distributor isa prolly bad

[Raf99]

it would be the cap off the new dist/engine, so its in good shape.
But ya, checking the wires and other stuff. I'll let ya know the results

is the ground on the thermostat housing conected. if that ground isn't connected you wont have spark.

o yeh that damn ground!!!!!
