Pinto EFI to carbs

[dogwood]

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.

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.

Has the pinto's engine loom been tampered with?

Just a tad yes....


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. ( 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.

well there's your problem - no they are not the same. The pinto EFI system uses the spark timing as a datum point to time the injectors. Without the correct dizzy nothing works.

You should be ok with the carb manifold gasket on the injection head, but you may find it doesn't last long before it leaks at the top. (the reason the ports are egg shaped on the injection head is so the injectors can fire cleanly into the ports) If it does go fairly soo, fit 2 instaed, the extra thickness will give you a longer life.

Strictly speaking the Pinto EFi distributor is not really a distributor at all, its a crank sensor or at least thats its main function. Apart from its solid shaft and the rotor arm theres nothing else in it that moves. It sends a signal to the ECU which then uses clever logarythms to work out engine speed and tdc references for both ign and fuel. The ECU fires the coil and the cap and rotor arm supply the spark in the traditional way. Cant remember on these whether they are banked or parallel injection. (banked = pairs of injectors fire at the same time or parallel = all together).

If you have been trying to run EFi without the EFi dizzy then that would explain why it no go though I'm surprized you could wire it all up

1.6 or 1.8 breakerless or points will work with the carb set up you have. I've not had gasket problems though I've used the earlier manifold and 38 dgas carb.
