Time for an undate me thinks.
This won't be pic heavy post unfortunately as I sorta just got stuck into what I was doing and didn't take many.
Whilst waiting for the dizzy I went about sorting the wiring.i bought the complete front loom as I though i may have needed to to keep the ecu happy etc.
Turns out from this loom
All I need was 3 wires with pins for the vtec stuff and knock sensor
As the engine I got was obd1, same as the original engine. The new ECU plugged straight in and there are spaces in the ECU plugs for the pins I didn't have. The original car loom fits the new engine sensors etc Pretty much perfectly. There's a couple of times you need to unwrapped the loom for more wire but that's as hard is it really gets.
Which I didn't expect so was a nice surprise
With everything wired in I was waiting for the dizzy to show up. I was beginning to have my doubts but I came home one day to this
So I plugged it in, excited to hear it roar into life.
Turn the key and nothing. Battery had gone flat.
Quickly fixed by using my other accord to jump and it cranked.
And it cranked and it cranked.it Did not want to start.
I was some what annoyed.
I went back to basics, did I have fuel?
Yup, I had decent fuel pressure.
Using a test light I checked to see if the ecu was sending a pulse to the injectors.
It was.
Next on the list was spark. I swore, fairly loudly. As this was the issue I had with the original engine.
If I had no spark I would have actually made things worse and not better by attempt this swap.
I look for spark at the plugs. No spark.
I YouTube how to test a honda dizzy.
Find out how to test spark at the coil.
No spark.
Now with these dizzys and from what info I gathered. No spark from the coil means either curse word coil or curse word ignition control module (worth noting you should check power to the dizzy before this step).
See has eurocarparts had coils available next day for £20. I went with a coil, I would of got a ICM to but they didn't have it.*
Fitted the new coil to the dizzy and retested. And can you guess what?
No?
No spark.
So I ripped apart the original engines dizzy for its ICM, no idea of it worked or not, but I was frustrated and wanted it started.
Upon removal of the new dizzys ICM, I could hear it rattle. Probably not a good thing. I gave the replacement one a shake and nothing. So that was promising.
What the ICM looks like and how the insides probably shouldnt look
I rebuilt the dizzy expecting it not to work. But it did
I literally took a double take.
I rebuilt everything and tried starting the car. Only to be disappointed yet again.
I had spark,
I had fuel
I had ECU command
Couldn't think of what I was missing.
So out of sheer frustration more than anything I attempted to start with full throttle.
she roared into life and I mean roared. No exhaust apart from the manifold.
(*A couple of days after I got it running I went to honda to see about getting a genuine ICM as a spare. Thinking they'd be about £40, turns out they know longer make them and when they did, they were £300!)
That got my mojo back big time. The rest was very straight forward.
I had eml of no air intake temp
And when bleeding the coolant I couldn't get the fans to come on. Turns out the plugs are very similar and swapping them over fixed my issues.
It now looks like this
All plumbed in and running quite happily. The dizzy needs it's timing dialed in but it's drivable and Ive done 160 problem free miles so far
I still plan on doing the nc500 in this but it should be a tad more fun now I've got vtec.
