RB25 wired up but no power

[chrispypunk86]

I just got my rb25 swap into my s14 done and I just tried starting it and it would crank over but it wouldn't start. The fuel pump wont kick on and I checked a few other things under the hood and there was no power to them. Wipers wont turn on either so I believe theres no juice to anything that I just rewired. I used the rb25 to s14 wiring on rbforums.org and like I said theres no power. Can someone please help?

Do the relays click when you turn the key to ACC and ON?

Is there continuity in the fuel pump wiring? Did you double check your wiring to make sure it is correct?

check your grounds and make sure theyre all hooked up. check if youre getting 12v to the eccs relay, then check if youre getting 12v to pins 49, 59, and 109. and if youre positive your wiring is all good then open up your ecu and see if everything looks all good in there. thats where i would start. good luck

I figured it out I never wired the hot wire to the injector harness wire. It said to wire it on a series 1 and mine is a series 2 so I didnt. So I just tried it and it got power. The only problem im having now is a rough hesitation/ miss when you give it gas. At wot the rpms drop and it starts to miss and then it will catch and rev up, probably because of my z32maf and i dont have anything to tune it yet. So I just ordered a stock maf since its cheaper than buying something to tune it with until I do some more upgrades.
