Now my RB20 won't start

[BoostFab]

found them the grey and brown plugs on mine are in the R/H whell well and feed into the fire wall. woo hoo. still haven't checked wiring at the 2 yet. i'll post findings later.

you will be focusing on the gray oval plug...as it's where the main wiring is....only wire on the brown plug will be use is the fuel pump wire (black/pink)

the black/white wire coming from the grey plug is cut and alot of other wires, as well there is not another side from that grey connector. WTF. So what should i hook this b/w wire to? any 12v or to the eccs or ign relay?

ALSO, from that grey plug where do the rest of the wires hook up to and what signals are they?

GENTLEMEN THANKS FOR ALL THE HELP..

the only wires from that plug that are hooked up are the red/black and red/grey stripe and they are to the eccs and ign relay.

I Traced the fuel injector wires from the ecu to the 7pin injector plug and i have continuity and the grey wire gets 12vdc and the other should be getting pulses from the ecu right? soo how does this b/w wire come into play? i thought just the grey wire was the 12vdc and the other 6 are the ecu ground(pulse).

i'll post up a pics when there's better lighting tomorrow!

reason for cluelessness i had paid a mechanic to do the swap for me with my mickinney motor mounts. The guy tells me it's pretty simple and since i bought the car with an rb20det in it he was just swap it out and viola good to go right. NOOOOO. i get the car back from them and the wiring job looks like sh*t wires just twisted together. so i go back in with environmental splices and put everything together according to the 8 step. soo now i'm just back tracking and i've only had the car for a week and i've got the ignition part solved. just need to figure out the fuel and it's done. all other wiring and sensors are finished and all harnesses are plugged in. this is the only part that i'm lacking soo far is getting FUEL FROM THE RAIL PAST THE INJECTORS AND THATS IT.

SO a neighbor of mine comes over and tells me that maybe it was the tps because one of the connectors had no wires going to it, so i look for an answer and well 2 harnesses on the tps is for an auto and one is for manual. then he tells me about fuel pressure from the pump and the pump operates and sends fuel but at what pressure i have no clue soo i just bought the walbro 255lph pump and nismo fpr.

first of all, you should go over your wiring, make sure it is correct. scan throug h the link in my last post and reference the information on there with your wiring.

hit me up on aim if you have any question.aim: b00tsfed

BE ADVISED MY SWAP DOESN'T HAVE THE OTHER END OF THE RB WHITE PLUG (MALE END) SO I'VE BEEN GOING DIRECTLY FROM THE RB WHITE FEMALE SIDE.

black/red from rb white to ka 6pin oval black/red

white/black - mine was cut already, what pin from ecu or relay? white/purple - heres a pic of my white plug. only one i have is soild purple.

wait a minute....are you wiring up the rb25 or the rb20????

sh-t...ahhahaah what i have been telling you is for the rb20...

i appreciate the help and please keep in mind i'm just an avionics technician on airplanes(wiring and radio/navigation). this is very new to me working with cars and the mechanics of it. ]

check the other post about the fpr i just did.
