318, 5.2L, 2BL 1987y Chrysler Engine with Electronic Fuel Control
- Thread starter Maksim
- Start date
The pigtail connectorat the rear of the engine should be for the oil pressure sending unit.
l'm not familiar with the late 80's models, but attached to the air cleaner - that box should be the spark control (as you have a carburetor on the intake).
I strongly suggest getting the service manual for your model and year.
Or maybe more knowledgeable answers from other members.

The computer no.longer connects to vacuum hose. Since you aren't using the computer get a new carburetor. The distributor vacuum hose will connect to the very bottom of it.
There should be a sticker on the hood that shows where all the other hoses connect.

Actually I will use Sparc Control Comp. , just waiting for new one to be arrived . Sticker unfortunately is missing...

In that case follow the sticker on the hood. It shows where all the vacuum hoses go.
I hope it was a fuel control computer same year or close to yours? The spark control computer was a bit different.

Yes its Fuel control computer. It has some numbers which you need to find the right one.
Eureka! Vacuum diagram
Found it! From Fuel control module goes under the air filter, and hose from air filter top goes to carb... Yeeee, thanks guys but if somebody has the same engine with Fuel control module - photos will be very useful to Mikes5thAve

The vacuum hose diagram changes. The bottom one is different then what you need. The top one might not be correct also (you should have more then one solenoid). Unless it's been damaged there should be a sticker under the hood that shows it.

I'm probably the only one here who is too lazy to switch over from the lean burn/spark control computer. I also have an 87. Right off the bat I can see that the carburetor is different from mine. I'm assuming that's because it was a Canadian or export model.
When I was digging into replacing my computer (because I found one cheap) I found there are different computers for the same year. I'm not near any of my parts books right now, but I want to say there are like 3 or 4 different computers for M bodies, and I think 2 of them are for 2 bbl carburetors.
Why are you changing it back? The regular mopar electronic ignition is pretty simple to work on. A lot easier than trying to recreate 80s technology.

Yes it is Canadian version . What about Engine Control Module - when i was ordering it from rockauto, there are maybe 6 or 7 identical , but when i started to look at numbers (OEM - Interchange Numbers) only one fits. So i hope it is the right one. The reason why i'm trying to recreate is that at very first time when i got this car - maybe 2 or 3 times it somehow was working , and engine works perfect - like fuel injected car. But it was only few times, after that it completely dyed. The guy who was checking it sad - that one signal is very wick (and its not from vires), so we decided to all this stuff and what can i say about it - it was never so good like with ECM module, engine was shaking, not much but each year it become worst and worst, also you need to be very careful with accelerating, because to much of it and engine stops. I tried to clean carb but it wont help much. And yes, the guy who did the work sad - that this carb is to small now, and i need to change it to 4bl. But then u live in Europe and almost every screw you need to send from US, pay customs , sending and so on, i didn't like this idea, for me - bring working ECM is easier than put new carb (it costs more) and when realize that you some few bolts a missing or smth. like that... So this is the story
If this wont work - well , maybe its time to sell it so somebody who will take care of it , so it is like a last attempt

I'm no expert, and it is very hard to diagnose anything over the internet, but it looks like only half the conversion from the lean burn was done. That old carb isn't helping anything. You can get a cheap 2bbl carb and see if that solves the problem.Yes it is Canadian version .

Check for any vacuum leaks. Check all your plugs and wires and make sure everything is connected right. Make sure the plugs are in and tight and the plug boots are snapped on right. Check your compression for each cylinder. The shaking could be a misfire or a dead cylinder. Then start looking at the timing. Start looking at simple things first.
