196 fuel injection help!

I just got a 196 with what I believe to be is a
fuel injection kit from here, when it starts it runs
okay until you start to give it gas and it almost
feels like it's bogging out, and smells really Rich
it pops a code for a temp sensor and that's it
no other codes come up? Any ideas or help would
be awsome thanks alot:yikes:
 
So have you trouble shot and repaired the temp sensor error?
That's the first place to start.

The specs should be in the parts required FAQ to measure the sensor with an ohm meter and the wiring can be checked also following the wiring FAQ. Yellow wire is the signal and black the ground.
Unplug the ECM to clear the code to see if it comes back.

What computer does it have?
Does the throttle body have 1 or 2 injectors?

Thanks for the info I will check when I get home today, another question is. Will the 345 IH v8 bolt to the 196 trans I have? If so will I need a different fly wheel and clutch set up?
 
196 bell housings are usually offset tilting the motor so I doubt you have one that will bolt to 345.

Timing is set to 0 with a little plug disconnected. It is usually brown wire white stripe. After setting disconnect battery to clear codes and look in the FAQ for initial set up procedures.
 
So digging into it a little more I found that the injector seems to be spraying spuraticly, not a tipical cone shape, an the timing is at 20, but if I try to get to "0" it idles low and pulsates, does anyone know what injector the use for the rochestor on the 196 kit (knowing what GM it came out of would help alot) any info helps alot thanks
 
If you really want help then you need to provide the info requested and reply the recommendations provided with the results.

If your going to do your own thing then just let us know what you found when you fix it.

Have you looked thru the FAQ's yet? Like the initial system setup?
 
Okay, so I checked on the info you asked for, the sensor has been replaced and no more code poping. The throttle body has a single injector in it. And the cumputer has no numbers or sort of identifying factor on it?

What I know
-timing is at 20
-GM style rochester throttle body
-if I try to bring timing to 0 it hardly runs,
-it's to Rich (smells)
-not poping any codes
-it idles but pulsates
-injector doesn't seem to spray right? Not sure on that tho
-I tried to match the injector up and found one exactly the same
but again I don't know exactly what they use for this kit
(injector size jet)
-I don't have any paper work on the injection system
 
The parts required FAQ shows how to check the injector part number. I assume you haven't done that.

The initial setup tells you how to set the timing and the idle air control along with the min idle setting.
I assume you haven't read that yet.

If you open the cover on the ECM there should be a label on the chip.
Post that info.
 
Saw this thread, what would you use for this setup?

I looked in the FAQ, but its for a v8 setup. Would like to figured out what donners would be good.

Thanks

hyjack over.
 
Craig, checkout the FAQ's on the bp. I have 2- 4 cyl systems documented there.

All the same parts.
I recommend a 2.8 throttle body due to it having 2 injectors.
I've done it with 1 but tuning can get tricky depending on the ECM used.

Unless it came out of a Scout II. I see way more Scout II 196's then I have out of 800's. And they are not tilted like what would have come out of an 800. They are flat just like the sv's and bolt right up to an sv transmission.

I don't know if it's mentioned in the facts, but we had a harness and computer that was made to fire 2 injectors, but a tb with only one. We ended up wiring the second injector into the first and getting it to fire twice as often. This was along time ago, so another work around May have been developed and listed in the FAQ's
 
My single barrel tb came off a fiero. Looks very similar to the 2bbl but only has 1 injector.

Whats the fuel system like? Size of lines, routing, filter, tank set up, etc...?
 
Bought this krawler from this guy and of course have the same problem.
The code reads, "coolant temp sensor high voltage"
this is the sensor

I replaced the sensor and it still reads the same code.
The sensor I replaced it with has a different head(does not tighten down by a nut)
I see the proinjection ones available from autozone.
Is there a special cts I need to purchase?
Thanks for the help!
 
There should be a picture of the proper cts in the parts required FAQ.
If you bought this Scout then you should go back and try to answer the questions I asked.
Like what is the code on the chip in the computer.

It sounds to me like there should be 2 cts installed. They kept the original that only goes to the gauge and then installed the TBI sensor(or maybe not) that is needed for the system to operate properly.


The cts should have a yellow and black wires going to it.
Look at the wiring FAQ to see the correct wires.
Then trace them from the computer to the sensor.

If you can, take some pics of the system and post them up or send them to me.
 
Well the ECM looks like a 1227165.
It was a pretty common ECM used for 4 cyl's and v8's.
You May want to call afi and confirm that it is the one they used for a 4cyl system.
That would let you know what will be needed for wiring diagrams and data logging software.

It looks like it has a programable chip (the sst) so that should make tuning easier.
 
Cool, I emailed them a pic of it and waiting to hear back from them.
Should make the process easier
your the man bill
 
U have a (7165 4cyl)written in black marker
a 68767 8815
a 16047243.
Guy at afi said is doesnt look like there unit.
But I emailed him more numbers!
So will a proinjection cts work for a afi unit?
Or all they all a bit different and use diff voltages?
Thanks:mad2:
 
Ok first you need to understand that your system is simply a factory Chevy 4 cyl FI system that was ripped from a car in a junkyard and adapted to your engine.

It is not an afi/proinjection/howell/anyone- made system.
Most simply do what is written in the FAQ's in this forum. They pull the system and tailor the harness down to what is needed and sell it as a "kit".

So for any parts for your system simply go to autozone or your favorite store and pick up the part for an 88-91 Chevy s10 with a 2.5l engine.
If the connectors for the sender was cut off then you can buy them also.
You can also hit just about any junkyard and get the parts.

You really need to look over the FAQ's and compare them to your system.
I would pay attention to the distr and ensure it is set up properly.
The only thing that will not apply is the actual pin numbers for the ECM wiring.
You should be able to go to the repair section of autozone.com and look up your actual wiring diagrams and even some troubleshooting tech all for free.
Since you bought a broke project you really need to go through it 1 wire at a time.
Making sure that each one is connected to the proper sensor or ground.
If no power relays are used, they will need to be added.
In other words....go through the FAQ's step by step using your wiring and verify everything.
It will save you a lot of frustration later.
