ECU removal

Hi guyz n Gals

 

Can anyone tell me how to remove the ecu out of the escort Mk6 at all :) cheers, ...

 

 

Why i want to remove the ecu is because... Ive recently fitted a mates escort with a new zetec lump, due to hers running dry of oil, but now for some reason its not sparking and theres no fuel coming through the injectors wot so ever, yet there is fuel gettin to the rail as this has been checked.

 

all wiring is correct, and has been checked and rechecked, everything lubed up, wired in and clicked into place... So the only other conclusion i can come to is that there is a loose wire near the ecu as someone has tried gettin it out before according to her... everything else works as it shoud, all sender units, fuel pump etc etc...

 

Even tried bump starting it over a 2 mile trek but no joy wot so ever...

 

 

So any help would be great :D :cheers:

If all you changed was the engine then you've either affecting the wiring somehow or your crank sensor/flywheel setup is wrong.

 

What was the old engine, what is the new? What parts did you swap over?

old engine was a 1800 Zetec Gti , New engine is also a 1800 Zetec (gti)

 

No parts been swapped over.. ive had all cables out before when she needed the head gasket doing, so i know there in the right place..

 

Do u think a swap in parts over from the working engine over to the non runner will help, if not out rule them parts?

As Stu says, no spark or fuel is almost certainly missing crank sensor signal, so I would double check all the plugs and wiring. If you have an analogue multimeter you could use it to test the crank sensor - connect it to the two pins - set it to 3v AC or thereabouts and you should see the needle flicking when the engine is turning over.

K cheers guys,

 

Ive swapped 2 wires round :innocent: ( flywheel & other, which fit perfectly both ways ) .. so im going to go for broke, and test it when me old man gets in as ive drained her battery now lol... :vangry:

 

But ill let ya know. ;) Other than that everthing else works A ok...

 

Cheers again :cheers:

I'm wonder other 2-pin jr timer connector is near the CPS.. i dont think the water temp gauge sender uses that connector from memory.

 

Nah ur rite mate.. The flywheel sensor is on the same harness as the fuel rail, & tps & icv, i think lol....

 

But anyhows its running :D :thumb: :rolleyes: :cheers:

 

But runs like a bag of nails... pulled out the plugs, plug 1 completely crushed onto it self.. replaced that, re ran the engine still runs ruff ( approx 500 rpm ) but no crushed plug this time :) get like a contstant compression hissing noise... i.e when u turn the engine over by crank with manifolds off & u can hear the compression hiss, thats what im hearing all the time... Probs an air leak somewhere, I cudnt see rubbish in the dark so ill check saturday sometime when im off work :) ermm at stand still, i put my foot down just a tad, and the rev's jump way over 4k, then back off to 500 - 800 rpm

 

took it for a little drive, going about 10 mph, then all ov a sudden it picks up lurching forward and dies again ... ive never experiecned any of these faults on mine before..

 

Im thinking as i know nothing of this engine's history i orta Strip it rebuild it go from there :), least that way i know wots what & then i can always change the stem seals etc at the same time :)

 

Then i guess i cud do a HOW TO GUIDE :) pefect timing lol

So what was the problem?

 

:blush: I got the fly wheel sensor mixed up lol... stupid that like coz both conectors fit the sensors perfectly :glare: So i think for anyones future reference tag the sensors as u take them off, dont assume they all have thier own special conector like i did :) :unsure:

 

Cheers again stu :cheers:
