Got questions and pics.

[1via]

First thing first, I replaced my ignitor today. I turned the car and some smoke started to come out from the steering column. So I took out the screws from the black plastic that surrounds and found nothing. I was trying to take off the bottom parts when the car stumble and then more smoke came out. Does anyone know what this is or have experienced this before?

Second, my solenoid valve has the blue parts where it has broken as seen in the pic.[IMG][/IMG]. Does anyone have an extra one that they would like to sell?

Third of all I wanted to know what this is in top of the ignitor? It has two hoses that cut off. I wanted know what they are supposed to connect to? Pic[IMG][/IMG][IMG][/IMG]

your second pic is the factory boost solenoid.if your running a after market boost controller you dont have to have it.

I have no clue what that thing on top of the ignitor is. As for all the vacuum lines, the only ones you NEED are a line running from the manifold to the fuel pressure regulator, a line going from the compressor housing to the wastegate actuator, and a line going from the intake manifold to the BOV. Nothing else is necessary for the car to run.

PS- Please tell me you have a uterus.

you notice the long nails too

CA's dont have factory boost control....not with that solenoid at least.

That solenoid is used for the intake buterflies. ( thats what its always been hooked up to in all the cars Ive seen factory ).

But the Book reckons its there to give a higher fuel pressure at start up????....cant vouch for that one

[capwred]

im sorry but thats what i was told it was.i guess the info i got back in the days was wrong.like i said im sorry for giving you the wrong info.

i did just look in the fsm and its called the pressureregulator control solenoid valve.but i not really sure now. sorry

PS- Please tell me you have a uterus. [/QUOTE]

Yes I do have one. Not that its any of your concern. The fsm calls it FICD Solenoid Valve. As for right now I dont have any boost controller but in a couple of weeks I will. I also dont have a Bov. Waiting to put my fmic on.

The solenoid in the picture located at the bottom of the ignitior is the factory boost control solenoid for Jdm's and on the Euro versions it is used as a hot start solenoid. The broken item in the first pic is the FICD solenoid. It controls idle when the a/c pump cranks on.

Dont bother with the vac connections to the solenoid if youll be replacing it anyhow.

Must use that pickup line next time i go to Malaysia

Could have been an emo guy, so I was just making sure. No big deal though, my mom has one too (allegedly).

[1via]

So I should replace it?

[datsunboy]

yeah, your broken one is a FICD solenoid, which turns the idle up higher when you turn the air-conditioning on......so its not crucial to engine running.

How do you figure that ( not saying your wrong ), but I have pulled apart a few JDM CA18DET's, ( in BOTH S13's and U12 bluebirds ) and that solenoid is used for the intake butterfly valves, and is not hooked up to anything to do with boost control.

also, check out the CA pinout diagram.....and follow the wire back from that solenoid, and you'll find it goes to ( forget pin number ) the Variable intake valve control on the ECU

I've got a ficd solenoid if you still need one.

S13 specific, there are up to 3 solenoids which are used. The solenoid located on the ignitor bracket is used as above, while the solenoid used to electronically control the butterflies is affixed to the vacuum tank bracket which includes the tank and 2 one way check valves. On Auto models there is also a separate solenoid which adjusts fuel pressure. This is also located on the vacuum tank unit.

As for the pic above, the ignitor and bits seem to be located on the wrong side on the engine bay, probably due to a conversion. Another give away as to the job af that solenoid is the different sizes of the vacuum lines. The large one 'T's into the turbo to actuator feed and the smaller one also runs to a 'T' which ultimately feeds back into the intake piping after the AFM and prior to turbo.

The english version of the FSM is actually only for the EURO version, not the JDM version.

[capwred]

al i know we hooked mine up to the to the turbo.and i wa told thats how it works.and it worked fine to hold the factory boost. then when i got my blitz twinsbc i took it out.

[datsunboy]

it'll hold factory boost fine if you hook the wastegate straight to the manifold aswell.

but thats interesting....Ive never seen that diagram before!by looking closly at that diagram, it looks like the wastegate is hooked directly to the pressure source, and that thhe solenoid is only tee'd off it.....is this to say that it "bleeds" air off to control boost?....or that its not actually there to control boost.

are you able to tell what pin both the "boost" control solenoid, AND the butterfly solenoid go to?

[niscort]

Yeah, it works as a bleed which varies boost pressures from 600mmHG(11.6psi) {when using high octane fuel or regular under 3000rpm and engine temps under 100deg} or 500mmHG(9.6psi) {on regular above 3000rpm and when engine temps reach over 100deg}. Confusing, as this information is plotted in graph format.

Ill have a look for those specific pin outs for you tonight.

[niscort]

boost control solenoid is pin 5 - light green(maybe, having trouble with the japanese character)

butterfly solenoid is pin 8 - grey

physical layout of JDM vacuum piping: click

a hackjob of the english EDM diagram to show the extra bits for the butterflies:

some day I may scan in my JDM FSM.. but I am afraid to damage it, it wasn't cheap I need to get a second one thats not in mint condition to rip apart and scan in.

[biosehnsucht]

oh and for the bit about smoke and steering column.. was this inside the car, the black thing that surrounds it being the steering column trim? that is very, very unusual.. and you might want to make sure no fuses have burned out and check everything out to look for what burned.. if it caused the car to stumble then perhaps something to do with the ignition wire from the keylock or the power wire leading to the keylock ??
