K swap advice!!

[StockieSi]

Sup ctv wiring up my k swap in a 00 civic using prc ecu when i go to ground the fuel pump still wont prime!! All grounds are good fuses and relays to i just dont know what else to look for the prc ecu doesnt have imobolizer so that cant be it any advice would be apreciated!!.

The PRC ecu will just need to have the fuel pump wire grounded.

Yeah i grounded it but still doesnt prime? I tried grounding it both from conversion harness and the engine harness still nothing!

You need to tap the loose fuel pump wire from the conversion harness to a15 on the stock ecu plug,it's a green/yellow wire.

If you did this and it's still not working make sure the main relay has power to the yellow wire and black/yellow wire with the key in the on position. If you do have power to those two wires and it's still not working try grounding the green/yellow wire from the main relay to a good chassis ground,this should turn the pump on.

If non of that works make sure the pump works. If grounding the green/yellow wire from the main relay works then the problem is either in the conversion harness,ecu or some thing you didn't do right.

I will try that tonight and let you know thanks!!

Am so confused on HR the a16 plug is where the a13 is on the pic above idk if a si a plug is wired out different but when i ground the relay and connect grn/yel wires only relay click fuel pump still doesnt prime!! Fml

[StockieSi]

So should i just ground the a1 from HR conversion harness grn/yel from engine harness or just the fuel pump relay?

Can you post pics of your conversion harness?

Thats the only pin with a grn/yel for fuel

Which harness is that from? If that's from the k20 harness it's the wrong plug. You need the one from the stock civic harness,it should be the only ecu plug that's part of the chassis harness. It looks like that plug in your pic but the green/yellow wire is 4 over to the right.

this is the diagram i used

2point1 the stock civic plug doesnt fit any of the ecu slots am using an 02-04 prc with 02-04 rsx-s harness
