Ok so I have been looking for the past couple weeks for a definate answer on what the wiring colors for 1-6 are but havent came up with anything to match what I have. As an intro the the car it is a S14 w/ RB20det swap which I bought preswapped and it ran fine. Then moved and it sat for a few years. I would come back and start her up every so often when I could get time off work. The car all of a sudden took a s*** and ive concluded its spark since im getting fuel to the plugs. It has nistune, z32 maf, rb26 injectors, quest alt and a few more things i cant think of. Just thinking theres something crossed in the wiring since the last time it ran it died mid driving and wouldnt start back up. These are the wires ive found vs what mine are.
What I've found:
1. Blue/Brown
2. Blue/Black
3. Blue/Red
4. Blue/Yellow
5. Blue/Brown
6. Blue/White

Now the wires that I have:
Blue/ Black with a Sliver marking on it
Blue/ White
Blue/ Yellow
Blue/ Red
Blue Solid
Blue/ Pink
These aren't in a specific order. Any insite yall could give me would be much appreciated! thanks

Wait. The car ran fine for a while, then it sat and started acting up on you? So I'm trying to figure how that's going to be a wiring issue in the ignitor. If the ignitor was mis-wired, it would never have ran right.

All motors need air, fuel, and spark to run. You've concluded you're getting fuel, but you haven't removed the possibility of something being off with the air meter. Try unplugging the MAF and see if it will start in limp mode. A lot of times when a car mysteriously enters into a non-start situation and it's meter related, disconnecting the MAF will show that the MAF has gone bad.

If it sat for a long period of time, make sure no critters climbed into the engine bay and chewed through anything (happens more than you'd think). Check the spark plugs and make sure they haven't corroded over or something or just fried in general. Also, it could be bad gas. It's likely that the car sat so long all the gas went sour and the car's having a tough time igniting it. With modern ethanol fuels, old fuel that sits tends to have issues with sediments and gelling.

Sorry I forgot to add some stuff. So I need the wiring cuz I have ls2 coils I wanna put on it. And I did a pull on it the night before it essentially died and it essentially snotted oil out of the pvc valves on the top of the motor (no catch can atm). rhat night when I got back I cleaned up the oil and was taking it out after I made sure the oil level was good and about a mile down the rode it died and wouldnt even pop start. I did notice the other day that the maf wiring was melted a bit. But it should still start in a limp mode with it unplugged like you said. And I drained the fuel and put fresh fuel in. Plus they are new plugs.
