Thanks Peter, I did get it working again, and YES CRXER, looks like there may have been a bad solder joint on the relay, i pulled the top off it and re-soldered all the connections, and tried again at midnight, this time i could hear the pump prime, so I will try and start the car again when I get home tonight.

Does anyone know if I can still use that original ignition coil feed that comes out from the firewall (the thick black\yellow stripe wire) to feed my current ignition coil? I would have liked to use this as I know it is switched by the ignition switch. (there wouldnt be a resistor anywhere for that? I rememebr all my old cars having one)

yes you can

as long as i has 12v then the IGN is on POS II and not on POS I you will be fine

Here's an interesting read from that website Chris:

Charcoal Canister

"The OBD1 charcoal canisters have three hoses on top while the OBD2 canisters only have two. The OBD2 motors lack the vacuum hose on the throttle body for the third hose. So I got a 96-01 Acura Integra charcoal canister. It is similar to the 96-00 Civic canister except that it has a larger capacity. Either canister slides right into your firewall mount and fits the lower hose. The lines on top of the canisters are marked "tank" and "PCV" (in this case "PCV" stands for "purge control valve"). The "tank" hose goes to the fuel line on the firewall and the "pcv" hose goes to the purge control valve in the center of the intake manifold. I wired this valve to the wiring for the old purge control valve, but unfortunately the OBD1 ECU doesn't control it correctly and you will get a surging idle. The AEM EMS will have no trouble controlling it. If you're converting your car to OBD2 and using the rare P2J 3 Stage VTEC ECU, then of course you'll want to use the OBD2 Purge Control Valve."

Might be the answer to your idle problem???

Peter

I am sure i have the right IACV, but maybe its dirty, or i got the hoses wrong? and my ECU is OBD1, its another thing to look at..

So ECU_MAN, that black/yellow stripe cable should just go to the IG II switch? if thats the case then i will connect it back up, i think cause the car died pretty much after connecting it, it made me think i blew the ECU up..
will put an inline fuse too i think
Cheers
Chris

a fuse would be a good idea, Im pretty sure its fused from the cabin fues box.

Cool, have got an inline fuse holder with 4mm cable pre-attached, should handle the current..

My only remaining issue now seems to be idling, when first starting the car, it runs for may 20 to 30 seconds, then starts the fast hunting, if I can this weekend, will trace the IACV wiring and make sure it goes where it should.

Cheers
Chris

have you wired up the MIL and ensured you have no codes ?

Not yet, but think that sounds like a great idea, rather than fumbling on

cheers
Chris

thats right.

dont guess and think its done right and try to fix problems caused by things not wired correctly
