I put a new fuel filter on it today, and I "think" the fuel system is now solid.

I attempted to start the motor. I got the "whistle" as the CIS primed. It coughed a few times but did not start (IMG:style_emoticons/default/sad.gif)

I stopped because I saw fuel coming out of the exhaust, so I hope I haven't buggered it up too badly. I am worried that this is a really bad sign.

Anyway, I am sort of out of ideas at this point. Anyone have any suggestions?

try pull the intake boot off the cis fuel distributor. Make sure the air plate lever thingie is not stuck. Make it can move freely. The gas out of the exhaust is probably due to the plate being stuck engaged due to bad fuel. If you do free it, pull the plugs and turn it over a few cranks, there is going to be a lot of fuel in the engine. Dry out the plugs and try again. CIS can be a fussy beast.

good luck

I was following Slits' CIS issues.

IIRC - he said to pull the fuel dizzy and clean it up. I "think" I have done that. Here's a pic:

That brass guy there in the middle doesn't seem to move at all. Is that what needs to move up and down? I think it's stuck up, which would mean WOT.

Any help is appreciated.

Thanks!

Joe, the center piston is what HAS TO BE FREE. It is the metering piston for the CIS. If stuck in the up position (pushed into the body of the fuel distibutor) you have WOT fuel flow, which is why you filled the exhaust will gas.

Cleaning that unit, the warm up regulator and injectors was what the post on NARP was all about. Tedious, but it can be done. There is a nut on the side of the fuel distributor that holds in a shim, spring and piston ... it is the main pressure regulator. If you take it out, don't loose ANYTHING.

Clamp the exposed tit of the center plunger in a vise and pull to see if you can get it out of the housing. Clamp only on the tit as it is a machined piece matched to the bore of the fuel distributor.

I will be at the shop today (Sunday) if you feel like driving to Riverside. I can give you a Fuel Distributor I have already cleaned up (bring your old one).

In lieu of that ... couple of cans of Brake/Carb cleaner.
Once you have pulled the center piston ... fill the cavity with brake cleaner and let it sit. Clean the piston carefully (don't scratch it) and set it aside.

Flip the fuel distributor over and carefully fill each of the outlets with brake cleaner and let sit.

Using a blow gun (rubber tipped is nice), start blowing back from the outlets on the top of the FD - don't use full pressure - trigger the gun slowly. When the passage is clear, you will feel air coming from the center cavity. Once all six are cleaned and clear, coat the piston with 3 in One oil and put it back in. Make sure it slides freely (the oil will give some resistance).

Pull the injectors with the tool I described ... straight claw framing hammer and wood block. Using the brake cleaner can with the red plastic tube, insert tube into inlet of injector and trigger ... it has enough pressure to overcome the spring inside. You will see the spray from the injector change from dribbles to a fine conical spray when clean.

The warm up regulator has a fuel in and a fuel out. Fill each hole with brake cleaner and let it sit for a while. Apply gentle air pressure with the gun until air flows freely through the holes (even in reverse). Once it's clean, you're ready to give the start a try. Warm up regulator modifys system fuel pressure according to temperature of the heating coil inside the unit and, depending upon the year, by vacuum also.

Oh, the car will run without the Fuel Accumulator, but will not hot start. It smooths out pulses from the fuel pump and maintains pressure in the system for about 20 minutes after shutdown. I bought one from a member for $75 and one off eBay for $65.

I'd love to come out and do a swap, but I have to watch the kids today.

(IMG:style_emoticons/default/WTF.gif) I don't get it. The post in your link follows the basic template almost exactly. And you don't need to follow it exactly for that matter. What you wrote there would be great as a tech article. In fact I'm going to need all of this info when I'm ready to get mine running. If you want to put it up as a tech article, email it to me. We'll work it out and get it posted.

We really should build one of these.

Extend the:

fuel lines
wiring harness
shift rod
throttle, clutch, speedo cables
targa top

We'd need to figure out how to mount the rear doors. (IMG:style_emoticons/default/laugh.gif)

No worries Gint .... your tag coding is a little different from what I learned and use. I just thought I would pitch a bitch.

I'll get around to setting it up 'cause it can save you $400 for a rebuilt fuel distributor and about $300 for a warm up regulator.

I also need to write up how one checks the system cold and warm pressures and how they can be adjusted with gentle taps from a hammer,but then you can get the CIS service manual too! It won't tell you how to adjust the warmup reguator with a hammer though.

But.............

It won't idle. It kicks over and spits for a second or two and dies. So I am not out of the woods yet.

Another problem, that I have been fearing, may have reared it's ugly head too. The starter wouldn't disengage very well before. I'd have to hit the switch from time to time to get it to stop cranking. I heard a nasty and assume that I might have dinged the flywheel. So I need to look for a starter now. (IMG:style_emoticons/default/headbang.gif)

Thanks to Ron, Slits and the Professor for the fuel dizzy. I think that really helped. I need to get a claw hammer with a wider split to got those injectors out and cleaned. That's next.

Starter is no problem Joe ... I have a few. Good job.
