Need help on 8 step wiring...

[fastback90]

I'm stuck on step four where you wire the grey wire with the black/red wire. I don't have a grey wire on my rb efi plug. Can anyone help me out? Where does the grey wire go? Thanks.

BTW I have a type 2 rb25 engine.

if you got series 2 then you dont have the gray wire

exactally, dont worry about the grey wire. if it dosent work without it we can help you fix it.

there are some small wiring diffrences with the type 1 and 2 wiring, the type 2 has no ignition relay or need for an external power for injectors. im assuming this "grey" wire does something related to those. that was my 1 complaint with the 8 steps wiring, he told what to do now WHAT each thing is.

i figured the same thing. i just dont have the balls to try and start her with out knowing what i might be not wireing. if you guys really think that it should be fine, thats good enough for me. i'll trya dn get it all done this weekend.

gani, do youknow what it conects to? i do have a wireing diagram for the rb25, but i dont know what series it is. according to that, the grey wire is conected to one side of all the injectors. does this make since to you? what are your thoughts?

the grey wire is the power wire to the injectors for the series 1.

[rcodea]

so since i have a series 2, it is another color? or are injectors wired differently? do i just need to not worry about it and start the damn thing?

Ryan

[Joe]

you dont have it.

the type 2's dont need an external power for the injectors.

and why are you afraid to start it? worst case scenario it dosent start. you arent gonna hurt anything.

[rcodea]

well, i didnt know what it even went to till today. for all i could have known, the damn thing could have gone to the fuel pump or something crazy like that. now that i know, i will be starting it this weekend, that way if i do have any other problems, i can fix them. thanks for the help guys!!!!!!!!

Ok.. I wired everything up according to the 8 steps wiring except for the grey wire since I don't have one, and my car still won't start. Can someone help me out...

[Joe]

um, check for spark, fuel, etc

[eh?]

won't start as in won't turn over? or won't run?

[gani]

check you ignition wiring from the key to the starter. or just turn the key to the on position and get a switch for the starter to jump the whole system. if this does help then go through your wiring again. does your gauge cluster light up when its in the key on postion? if not check you wiring ,battery,grounds

[crxcess]

yeah, we need more info on exactly what its doing and what it isnt.... spinning? sparking? fueling? mass air connected?, all piping connected? etc...

Firured it out guys... My spark plugs was covered in oil... I just cleaned them up and it started right up...
