The head code should be located above the Cyl #2 and #3 exhaust ports. What do you see there? You'll probably need to remove the header heat shield to see the code.

You don't match the ECU to your Civic trim when there's been an engine swap. You match the ECU to the engine.

And do you have an auto or manual transmission?

In your case, the head code is located above the Cyl #3 and #4 exhaust ports.

Can't clearly see the code -- Is it PM8-1?

Okay, you have a complete D15B8 engine, so you need to buy a P05 ECU. Any USDM P05 ECU should do because the D15B8 engine only came with a manual transmission.

I got the ECU today and put on and started right up! Thanks RonJ for all your help! One more question, the CEL stays on, probably wasn't on before because back fuse was blown. So I can just test it with paper clip to harness and count the lights, correct?

NO power to fuel pump

Ron,
Have same problem but don't exactly where your talking about main service connector and relay. I do know my way around tools and cars but, I have never worked on a Honda. So my first question would be (referencing this post) when he said he jumped pin 1 & 7 and 5 & 7 are you talking in engine compartment at realy panel or at ecu area. Although I need to check the ground at thermostat, and the ground to body continuity at pump still I just want to know where im going next to jump pins. thanks and wonderful help with the guy on the same problem:cool:
