Was the 84 FI? or was it the CCC-computer controlled carb?


You might want to check what your going to pull!!
I would think the earliest year I would look at would be 87.
You may get a system but you will still need tech support or may need a chip burned for it???

The Knock sensors are in the head ot the block not the manifold.


My rule of thumb for pulling a system is to follow the engine harness and if it's attatched then I pull it and take it home. When you sort the wiring harness out then you can tailor it down to whats needed.

Better to have more then less!!

The extra relays and switches may come in handy later!

IIRC yes. It was the low level line that just went in and straight to ground.
I think I posted all the diagrams up here.

It would be nice to be able to post a pic here instead of a link......

But I only support you guys with knowledge...not my money!!!

Pontiac 6000
1982-1991 LR8 TBI "Tech IV" 2.5 L (151 in³) I4

I hope it was FI! Like I said, if not, I'll just have everything and I can make a spacer plate (if I even need to!) to mount it on my current intake manifold... either way its not a big deal... just if this matches up this will be an INSANELY easy bolt-on job! "Its the SAME THING!"

Thank you, that makes sence for it to be in the head/block and not on the manifold... hows it tell if there is knock in the manifold? lol

Yeah, I was thinking of doing that lol... I don't want to have to run back or accidently cut something out of the harness when pulling it... just take everything lol

Anyway, I'm going down in a few hours, I'll let you guys know tonight what I got! (Hopefuly I'll have something... there better be a FI 4-Cyl Iron Duke out there!)

I did a little research on the A-body forum I go to for my '89 Century and it looks as though the 2.5L was TBI from the start in those cars (1982). I think there were changes of some sort in '85 in '87, though I'm not sure what they were, or even if it was with the FI setup at all. It's safe to say TBI was at least optional in the '82 2.5L A-bodies, if not standard. The V6 (2.8L) in those cars were carb'd until '85 though.

It's interesting that those cars, like the early YJs, got FI from the start with the 4-cyl, but went a few years before the 6-cyls got it.

Ok guys, I got everything I need hopefuly! I'm gonna be posting pictures in a few minutes... then edit this :P just excited and couldn't wait

BTW The Donor was an Oldsmobile Cutlass Cierra, 1989...

EDIT: Here it is! (Well part of the pics, more to follow)

My Jeep Site

Click on Upgrades at top, then the TBI stuff at the top of that... or... for you lazy ppl

Lazy PPL Click Direct To TBI Install

Could someone pay specific attention to the "ECU"... is that right? That doesn't look like any of your guys' ones?

BTW, I will be taking more pictures of the Dizzy (Distributor) assembly, the wiring harness, etc. later on... I'm gonna need a lot of help understanding the ECU and Wiring Harness... I'm also gonna buy a manual that has a very nice wiring diagram from the ECU out (if I can find one) for an 89 Olds Cutlass Ciera.

O2 sensor question

I am about to install the o2 weld ring in my exhaust and was wondering if there was a certain distance that the single wire o2 sensor could be from the exhaust manifold. I have the hole in my exhaust for the pulse air system still but it has a bolt welded in it to cap it off. I was just going to cut it off flush at the exhaust pipe and weld the o2 ring in there, but its about a foot away from where the head pipe connects to the exhaust manifold. Is that too far? Should I go with a 3 wire or 4 wire heated 02 sensor then if its too far away or will the one wire 02 sensor be sufficient?
Thanks,
Kevin

The 1 wire will be fine there.
It needs to be mounted side ways ot pointing down.
You don't want it pointing up at all to prevent any moisture or junk from settling in it.

Guys have used 1 wire in headers collectors but some drop into open loop when idling due to the sensor cooling off. That's why the 3 or 4 wire is better there.
Keeps it reading consistant.

Alright I miscalculated the o2 sensor will only be about 6 inches from the exhaust manifold, I'm good then thanks Bill.

Just wanted to double check this 8 pin ignition module wiring. The large cap HEI has the 3 prong plug then 2 single plugs. Its labeled like this:

C- Gnd B+ (3 prong)

Tach Batt (2 single plugs)


I know where the tach and battery go, I'm leaving them alone but does C- go to the C onthe ign mod, and does the B+ go to the + on the ignition module?
Thanks,
Kevin

If you are trying to use the HEI coil in cap distr for the FI then you need to convert the distr from the internal 4 pin ign module to the 7 or 8 pin ign module.
You can not simply hook the connections on the distr cap to the 8 pin module and have it work.

You will only use the 2 wires that come from the magnetic pick up inside the distr that will get hooked to the P and N terminals on the new module.


distr

I found a harness, sensors, Throttle body, ecm, hei dist and coil for $100 Will this work on a 304 and is this a pretty good price?

Bill,
Sorry, I didn't clarify that I have the 8 pin mod. I have the diagram for it but some things were a little different.
I have it set up like this
the 4 prong plug (GBRE)goes to the ecm
P,N to the pickup
+ and C last 2 I wanted to doublecheck.

On the diagram it has the ign mod + going to the C+ on the cap and the C going to the C-on the cap. The only markings on the cap are the C- ground and B+



So does C go to C- and + to B+?
Thanks,
Kevin

Sounds pretty good to me but you didn't say what from!!!!

Still need:
A fuel pump $75

Yep.
The C is the neg - side of the coil(same as tach) and the B= is the pos side of the coil. (bat) This is also tied to the ign sw 12v.

I would think you would be able to use a meter and read between the C+ and ign +
and
between the C- and the tach terminals!!
