Shutoff circuit
Shutoff circuit
Let's start this over. What is all involved in the shutoff circuit?
I could give a rip about anything creature comforts. But I would like the car to shift and turn on and off.
Any good explanations or diagrams?
Here is another diagram where I have no idea what '1' or '2' are.

So the goal is to delete egr and the 3/2way switch. This is the new thread to avoid visiting my last one that's full of aggravation and confusion.
1 and 2 is the actual ignition switch. There's a valve on the side of it (1). Not the most clear diagram, it's really simple if you look at it in real life.
Define "I want it to shift". It's pretty easy to bypass the transmission and only enable shutoff, but the the shifts will be jerky.
Also, I don't see EGR on those diagrams...
I mean I have the trans modulator connected to the VCV.
When I got the car the other day it would shut off.
Then I tried to hook up the trans modulator. Thank goodness, now shifting is much smoother. And I put a blockoff plate on the EGR. Also pulled off/pluged vac lines from the ARV and EGR.
Now the motor will not cut fuel with the key.
It's probably not plugged in right. If you have enough vacuum for the trans then I'd think you'd have enough vacuum for the shutoff.
Course if you want to get serious about it you should use a vacuum gauge, you're not gonna get far past identifying obviously open connections otherwise.
About right but that diagram is not for '85 models.
Will check how much vacuum is coming off the vac pump tomorrow.
Then we can start from there. Till then there will be a lot of hood popping.
Its pretty simple man. Can you get some better pics looking at it from the front of the car?
Everyone says it's pretty simple. I am taming my frustration. First step is to test how much vacuum the pump is creating. So, I can do that and we'll go on from there. Pics and all.
Check the pump. Eliminate all but the shut off circuit, work your way back from the shutoff pod on the IP with the mighty vac. Its really easy to get the brown vac lines backwards at the ignition switch.
Compared to electronics, vacuum is pretty dead simple. Ask me how I feed about the electronically controlled trans in my Eurovan.
You said the car shut off before, so its not the vac pump...
Psi, Vacuum lol
Shoot one good pic and I'll tell you how to run them!
What did I write that wrong? negative pressure/ vacuum -22psi , -1.5bar
You know what I mean, right?
I'll go get the pic.
locks are not part of the shutoff circuit.
There isn't anything hooked to that tee. I refer to that as the first tee after the vac pump makes the vacuum. Not as the second tee from the brake booster. As per my last post.
Well Vacuum is measured in Inches of mercury (in hg) not pressure. When you say 22psi, you mean 22" ... 24" is about the most you'll see so your pump is doing just fine.
That is an interesting vacuum line to the brake booster. There definitely shouldn't be any open holes or vacuum will never be achieved by the pump.
Normally, both connections to the main Vac line are at one spot with two different sized orifices... I dunno whats up with yours but you can see in the crappy pic of mine that the second line connection (closest to brake booster) is used solely for the shutoff circuit. It goes into the cab via the brown line and comes back out via the brown line which goes to the shutoff. EDIT May have this mixed up too
The line closest to the pump (first connection) Tees and goes to two things... 1. VCV with the inline Dashpot (that you are missing) and 2. down to the trans modulator (I think)
Then out of the bottom of the VCV you have both lines that go into the car, Green w/ yellow stripe and black.
NOTE: I may have the black lines mixed up, Everything is apart on both cars right now. Just try different combinations until the everything works right.... shifts and stuff.
At least this will get your car to shut off.
I do have the dashpot now.
That pic looks like the 4 way at the top of your VCV has 2 openings not connected at all. Is that right?
Also, I have that green yellow stripe but no black is around. Have mine looking similar, we'll see how this trip to the grocery store goes.
The 4 way on the top is plugged on the left side and on the right side has the black line that either goes to the inside of the car or to the trans I don't recall.
Sorry I didn't have a better picture...

brown blue stripe --- fuel shutoff
top of VCV -- trans modulator, second feed from vac pump (is this right?)
bottom of VCV -- ??????
can we try and fill in the ?????
and correct anything else I am farking up
I do see that there is some lines disconnected from that first feed. what should it go to?
