Pinto EFI to carbs
 

After spending all day sosiging around with the EFI electrics
on my 2.0 Pinto, and not getting a spark, nore nuffin
I'm almost at the stage of giving up on it.

So question:
I have a Weber carb on a Pinto manifold, From my 1800.
Can I do a straight swop from the injection system to the Weber?
At least I know how to wire up the non injection system.

I havn't got time to go megajolt system,
So looking for a quick option....Stonleigh approching fast. :eek:

Hi David
There is no problem with the carb. My pinto was a injection. You can put the dizzy from the 1.8 and run it standard.

There are some cheap twin 40 webers on ebay. Take a look.:D

Has the pinto's engine loom been tampered with?

TT

Just a tad yes....:rolleyes:


I cut and shut the wires to make them fit.
Think my joints are all good, but I just cant follow a wiring diagram.
Spent all day trying to get a spark.
Trouble is, there are just sooooooo many wires from the black box.

I'm going to try again tomorrow but if I have no luck then I got to look for an easy answer.

So my main question at the moment is.
Can I just unbolt the fuel injection system and bolt on the weber?
(It's a downdraught. forget which one at the mo,)
I realise I cant use the fuel pump. is there a place to bolt on the mech one?

I've had a sherbert or to so may not make much sense at the mo ....hic.:rolleyes: ( Bad day, and fed up)

Arn't the dizzies the same 1800 and the 2.0...I've used the 1800 one coz it looked cleaner

Hi
You can put the pump from the 1.8 you will need the rod that pushes it. there is a blanking plate over the pump out-let.

Im not shore But do you think you mite need the key to go with the ECU.
My dads old sierra did.

????? key?????

The key would have had an immobiliser in it. You would need to tape it to the top of the ECU.

Nope, no special key.
or anywere to tap anything in.

But thanks for the thought

HI Dave
I did mean the ignition key. The car would have come with two black keys and one red key. The black key had an immobilizer in the top. The red key was to reset it.

Sierras never came with transponder imobalisers.

I would find a good uncut loom.



Personaly I would rebuild the loom, but I do have diagrams and an idea what I am doing ;)

TT

Im sorry TT but thay did have transponder imobalisers. Been a long time but my dads sierra had it. late pinto EFI.

I have a diagram......Thats just confusing the issue....:D

I need the motor to be running by he weekend
to stay on track for Stonleigh.
So don't have time to spend ages on the injection system

I'm afraid I'm back to my original question.
Can I fit the Weber and manifold from my 1800 Pinto
straight onto the 2.0 and it run OK?

YES! It will be fine.

The PATS transponder impobaliser system was introduced by ford after production of the sierra ended.

The 2.0I Pinto went out of production in 1989, 4 years before the end of sierra production.

There is no way a 2.0 Pinto would have had a Transponder Imobaliser, in fact by the time the last 2.0 Pinto Efi went out of production I am no sure any manufacturer had introduced mainstream transponder imobalisers intergrated with Keys.


Pats was intorduced 94/95 with the Mondeo, MK5 Escort, and Scorpio.


TT

In fact,

A 2.0EFI pinto would be a pre 90 spec, it would not even have the door operatesd alarm imobaliser of the 90 spec DOHC.

The only system fitted to these cars may be the ford optional remote alarm system which was very rare.



TT

I would say it would run, but the jetting will be wrong. Your still going to need to get it sparking too.

TT

That should be the easy bit.
I'll just fall back on my old wiring diagram.
I can follow that......:D

Which module do you have?

TT

You should be able to get a spark from teh EFI's TFI module as long as it has power and ground.

on the TFI

Check there is +12v at the black
Check the brown is grounded

with those the engine should at least spark. and with a sniff of easy start it should fire.

TT

No idea..

I've got the one that came off the 1800.
And the stuff from the 2.0.

I just dont do leckytronix...:rolleyes:

Sorry missed your second post.

Don't even know what the TFI IS....


Explain......SVP

The ignition amp module, oblong thing about 3x1 inches

OK Im with ya now.

So does that work like the "Ign Modulel" in my diagram?

And the big silver box ( See I know all the techy terms)
Just control the fuel system?

More or lesssiy..

Unlike the ESC-2 on teh 1800 pinto the TFI has no idea about anything other than a distributor signal.

ESC2 gets vacume load data and can work out the spark timing.

TFI can't work out anything other that static spark timing on it's own. the TFi will spark at a preset timing interval if left to it's own devices. it does however relay the PIP ( Profile ignition Picup ) signal from the dizzy to the silver box ( the EEC-IV ECU) which process that data, combines it with the data from the coolant, air flow, air temperature and speed sensor. and then sends a SAW ( spark angle word ) back to the TFI to fine tune the spark, and at the same time controls the injectors.


Fuel injection of this era is very simple yet very effective. Modern systems are not vastly advanced, usualy just adding emissions control valves and sensors.

I remember the days of points & condensor, I could handle them :eek: :D
Good luck David :)

cheers
andy

OK thanks TT.

Think I have a better idea now of what I'm looking for.

If there is no spark then it's the fault of the TFI.
And not the ECU, which is where I was looking.

So back to you earlier post.
If I check power and earth to the TFI is ok
and still no spark then its coil end not ECU end

If that is correct then I'll strip out the loom again.
And redo the TFI to coil and dizzy connections.
And ignore the ECU for the moment.


It's half past bedtime for me.
So logging off now.
But will log on again in the morning.
Then I can digest what you said with a clearer head.....:eek: :D

Yes..

As a start, short the coil -ve to ground manualy to induce a spark and test teh coil

TT

How's it going with your electrics David ?

Let's hope today has been a bit kinder to you mate :) :)

Thank's for the thought mate, but not even close....:mad:
Wasted another day and still couldn't sort it.

So finaly given up on the bl**** injection stuff.
Refitted the Weber and 1800 wiring.
Had it firing up right off.

Main thing is, if it goes wrong at least I should be able to fix it.
If the injection stuff packs up I wouldn't even know where to start.

All I got to do now is get a manifold gasket.
The injection one ain't no good with the carb manifold.
Found one on Eblag so should be ok

Brings up a question for those that know:
The injection head has that oval/egg shaped inlet.
I will be OK with the round inlets on the carb manifold wont I??????

Going to be in the same boat as you mate .... I am starting with the modern injection route .... Gonna be B*****d if it goes wrong at a later date :eek:
Could write all I know about injection systems on the back of a stamp :o

I assume the shape of the inlet ports on the injection head are all about air flow .... Being as you are using carb, I doubt there will be quite so much demand for such a smooth air flow.

You may find that the carb is a little under jetted for the extra 200cc though .... Guess you won't know the full efect until you give it a test drive mate ;)

dave when you come back bring the injection stuff and i will learn you how to do it :D

if you cant be bothered then im sure i can get you a session down ATSPEED on their rolling road to set the carb up proper so it dont go bang.

failing that i could always sort you a megajolt and bike carbs.

Now there's an offer he can't refuse :D :D :cool:

EFi is simple.

I hate Carbs. That why I have fitted a Polo GT 1.3 Injection engine to our MK1 golf. I could not get it to run well all the time on the carb. 1st time I ran the EFi lump after a year out of a car it fired up and ran spot on.

TT

Better beleive it....:D


Cheers Ash your a mate.
Did tell ya I don't do lektrix.....

I know the coil is OK coz getting a spark with the 1800 stuff.
I know the wiring is ok to the TFI thingy.
Coz I pulled it all apart and checked it with the digi.
So wondering if I bu*****d the black box.

David.....

sorry mate but that statement has just had me in stitches :D :D

another long day, i,ll get my coat :o

glad you got the lecktrikery sorted :cool:

cheers
andy

Simple for you. I've spent 2 days on the bloody thing.
Just don't make sense why there is no spark.

Got a spark first hit with the 1800 stuff.
It's just a poz/neg and the 3 wires to the Halls....done!!
With the injection,I just got a mass of wires with no idea where they all go, or what they do

Well not sorted, but certainly closer.
Defo think I need to use the old KISS (Keep it simple stupid)

snap, like i said previously....points & condensor & I had a chance with it,

anything else & i,m baffled with leccy stuff :o :D

looking forward to seeing your car "again" David :)

cheers
andy

Me to......:D
Getting fed up with looking at a garage full of bits.
Not one of my better ideas to do a rebuild.
