nedd help identifying weird parts from the donor
while taking out the engine i wondered if i needed that computer looking ecu which is connected to every single bit of the engine. five cables go to
the carb, another two go to the block, another two to the dizzy, etc etc...
 
engine control unit
another thing.... what is this??? it seems fuel goes in some way, goes out to the filter another way and a third pipe is there for what....fuel

The top one looks like your ecu and the bottom one is part of the emmissions recycle thingy which I think you can bin.

When thinking outside the box doesn't work any more, it's time to build a new box

The bottom is the fuel return. Keep it although you may not need it depends on your setup.
Top is ecu keep it and all the loom to the engine.

oh right so the ecu can be replaced by a megaspark or megajolt for carb engines? didnt know that...
thought there was the possiblility of having the pinto running all by itself.. no electronic gizmos. of course it would have to be perfectly tuned.

Most likely one of the late carburettored Pinto's that had an ECU controlled carb e.g. stepper motor to control mixture and idle speed etc.
Idealy you need to keep the ECU and engine loom, or replace the carb with one of the earlier purely mechanical types.

Is your engine a 1600?
It would appear that your donor was fitted with the e-max system. The ECU was known for being overcomplicated (hence the many wires) due to its focus
on economy (<------ DIRTY WORD!).
One option would be to get a Bosch electronic dizzy and iginition module from a standard pinto. Other would be an after market option like others
say.
The second photo shows the fuel/air seperator which incorporates the fuel return system. This will not be needed if you run twin carbs but i would
keep it in storage for now in case you have running problems.

in my experiance keep the ecu and wiring harness and plug as they are like rocking horse sh** when you try and find a sierra with one on. i am using
this set up still with twin webers and it is working fine. i will get round to changing over after the summer . cheers scott . if in doubt keep it .

yep i thought it might be somewhat valuable as i would have never thought of a sierra with carbs and an ecu... gave the haynes manual a peep and it
does seem to control everything the engine does...
the engine has a few bits and bobs that the haynes manual says its from a cvh...the previous owner probably wanted it to be a cvh but just couldnt
afford an engine overhaul
the book said the second thing is a vapor separator and it improves hot starting qualities....i'll just keep it
thanks!

E-MAX purely refers to what Ford did to the engine only. They all used a common 2.0 litre blocks, cranks and heads, the variation in engine capacity
was acheived by changing the bore size to give 1.6, 1.8 or 2.0 litre capacities.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

If you've room for the ECU then there's no reason not to keep it. To replace it you'd need a new dizzy and carb etc to run any other
setup. We had it running on ours as Ford intended and it run very well and reliabley as it had auto choke etc.
The Fuel Vapour seperator (regulator maybe) is well worth saveing as well, we've never run without it but i've heard of people putting
them back on and getting an extra 10mpg out of the car. Maybe the float chamber in the carb isin't capable of shutting off the folow of fuel so
it bypasses back to the tank through the valve or of you haven't got one just throws it down the cylinders!
