ED with D15B7 injected wiring help

[tseesinngwailo]

Thanks for all the support guys, I will take some photos tonight to show you the setup, and yes, i have played around with the dizzy to see if different position changes anything. Plugs looked OK (dry from memory), but maybe i will get some new ones.
Now, interesting question..
I have spark when its cranking right, so if there was something that wasnt connected like the Park switch, wouldnt it not give spark when cranking? as I thought the ECU controls the firing of the coil? just a thought
Jason, maybe you DO have to come over
will have another play tonight, see what happens
Cheers

u'll prob find ecu will just fuel cut only if no park switch/whatever input,but hey,i could be wrong again lol.
see if u can hear injectors while cranking

just pm me if u want me to have a look

Park Neutral Switch only kills the starter motor,

If all is well it should fire. You really need to wire up the main relay as it feeds power to the injectors and ECU as well as the pump.

Hey All, SUCCESS!!!!! well sort of...

I found the main issue I think, it was from one of the drivers side plugs, the +ve feed to the injectors! had some issues with the PGFM relay as the numbers seemed to be different on the bottom compared to wire colours, my relay was from a Prelude I think, if that makes a difference..

Problem 1: it idles, but keeps going up and down like its trying to decide where to sit, like someone was tapping the acc pedal constantly, but if you push down on the pedal it revs up very smoothly, so maybe i am still missing some sensor wiring?

Problem 2: and this is a big one...
After running for a short time, it started putting thick oily smoke out the exhaust, not a little bit, but the sort of thing James Bond uses to crash the cars chasing him, it covered my entire backyard and smells like burning oil...

Any ideas as to how oil is geiing into my cylinders? as it doesnt seem like a bad air/fuel mix.

hang on, just as I write this, remembered my fuel might be dirty as i think a litre from my gerrycan was 2 stroke mix, hope to god its all it is, will drain the tank and try again

Any ideas on how to clean the tank

Otherwise, I may have a dud engine.. at which point I will scream

Thanks for everyones help, I am not out of the woods yet, but at least the engine started, very happy

2 stroke mix ? thats got oil in it son. Surprised it starts at all.....THAT is something you need to address ASAP lol. Put some decent 91 RON in it asap.

[tseesinngwailo]

Yeah, know now its probably the cause of the intense smoke, just didnt think of it as i needed a gerrycan in a hurry, will know once i drain the tank and start again. It was beautiful to hear the engine running, almost there lol!

Probably a vacuum leak somewhere. If the engine is 'hunting' then you have a leak so check all vacuum hoses, everywhere. I had a similar issue when I did the B16A conversion and found a vacuum line not connected at the back of the inlet manifold.

check the ECU for codes now, and make sure it runs with no fault codes.

two stroke will make the engine smoke, also if ur last engine blew then the exhaust could be filled with oil or coolant and cause the smoke. a nice drive will fix it,

you will want to drain the fuel tank to get rid of the two stroke fuel.

I have drained the tank, and put Shell Vmax or whatever its called, the smoke is less, but as you say probably needs a good run, will be concentrating mounting the ECU (i have to drill a hole in the firewall for the loom) and putting the wires where they need to be.

I have an issue with the PGFM relay, the numbers dont seem to correspond with my diagrams, did Honda use different pins between models?

[CRXer]

the starter input pin changed positions between obd0 & obd1 relays or there abouts.

the rest of the pins are the same position but just different number layout.

plugs wont fit between relays either,u have to repin matching plug onto the car loom.

put up a pic of which relay u have.

[ECU-MAN]

the numbers under the relay dont match what is in the schematic

you have to either figure out the relay or I can give you a brake down of the relay pins

[tseesinngwailo]

Thanks Guys, will post some pictures tonight, should hopefully have the loom mounted and ECU inside the car by the weekend, then will wire things up properly.

Desperately need this registered within the coming week

I really appreciate the help and advice

Cheers
