No idea..

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

I just dont do leckytronix...

Sorry missed your second post.

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


Explain......SVP

[twinturbo]

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
Good luck David

cheers

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.....

[twinturbo]

Yes..

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

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....
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??????
