Alright I know this isnt the right section but I figured it would get more traffic but if mods feel the need to move then go ahead sorry about that. But I have a 1990 hatch with rb20det swap, but it did not have a engine harness. So I picked up a 100% stock harness and that is re wired and all that stuff and as of now I'm not getting spark and my fuel pump isnt getting power. We ran the pump to a battery and the pump works fine (warlboro 255 btw) but it will not get power we changed all the relays to it with known working ones and still nothing. And I saw on a guide for the wring that there is a pink and black wire and thats for the fuel pump near the dash plug. Well i can't find the other black and pink wire to connect it to:( so that would be my problem right?

And for the spark we ran the pump to get gas to the injectors and all of that and tried to start it and it is not firing at all. And yes we have the 2 green relays in the harness so I'm stumped

Anyone have any advice I want to drive her :frown:

Ah, Did you connect the orange choke wire to the orange wire between the 2 green relays under the dash?

Fuel pump black/pink wire is on a brown connector near the battery. Thats where you connect to from the ECU. That should be about it. send me a text 843 822 5908 and I may be able to walk you through it, and yes this should be in the rb section!

More traffic to a post isnt necessary a good thing, you are looking for traffic from the RB section where more people visit that know or may know about this :-)
