RB25 S14 Wiring Woes

OK, so today I decided to wire in my wipers for my RB since the snow is starting to come in.
Turn the key on, wipers work...

We wired everything up, and then go to start the car and it sounds really odd. Kinda a rough idle. It was cold out so the car was idling a little higher. Drove it the block to my house from my friends where we did the wiring and let the car sit and idle while I pulled the ecu and dash plug back out. While I was doing this idle was changing the whole time. It'd get real rough, and stumble, and then catch, and then soemtimes idle perfectly normal, it was only doing this when i would move wires around...

I kept trying to mess with wires and then it fianlly just stumbled and died.

I tryed restarting the car but nothing. Just cranks. Fuel pump IS NOT priming.

So far Ive disconnected the wipers completely to rule that out.

So i take out the fuel pump fuse, good. Crank the car without it in a few times. Put it In, crank more, still nothing.

I go through every single wire that I have (from doing to conversion), and every one is good. Take the top off my ECU red light comes on with key on, and no burnt spots or anything that looks peculiar.

Could one of my relays gone bad or soemthing, or soemthing worse?

Any ideas/advice

thanks guys

OK so I just went out and messed with the car some more.

I had a spare relay and i switched it with my fuel pump relay and nothing.

And weird thing

After I turned the key off one of the relays kept clicking on the passenger side. I heard one of the relays clicking. and the ECU light stayed on with the key totally out of the car.

It kept clicking. Id take the relay out, and itd switch to the other relay and start clicking. Put that reelay back in, and itd switch back. Red light on the who0le time. Only way to get it to stop was taking the positive side of the battery off.

What the fuck is going on.

Only thing that i can think of is how I have my power for my injectors hooked up. With an RB25 is an S14 I was told you have to give them a key on 12v source so I tapped into the black/red wire on the ECM relay...

Any help guys?

Found my problem out

Wiring pin in the dash plug for the fuel pump was way loose. Fixed it and the car started to idle, but still like it had a miss.

Started messing with wires and when I came to my injector wires by the ECU and moved them around, the idle cleared up. But it wasnt a reliable idle.

So I turned off the car, peeled back the tape from them out about 4 inches from the ECU and the idle is totally normal now no matter what.

Weird huh? I know there might still be a problem. Anybody got any ideas lemme know.

BTW, might add, my injector harness had been cut when I got the motor, so I had to repair it...
