put a zetec in the g/f mk4 escort wired it up and it run but woudn't idle at all, then got it to idle it cut out and wont fire back up i have fuel and spak just wont fire up, been told it could be ecu any 1 else got a idea,

engine has only been taken out of a fiesta xr2 and fited in this and was all runing well

 

Does it turn over?

 

yeah turns over delivers fuel and spark just wont start

 

check all the connections and you may of flooded it trying to start it.

 

checked every thing, even remove the plugs cleaned them let it all vap off and tryed again

 

maybe you should try compression testing each cylinder.

 

done that too mate all fine

 

Keep it simple. It is unliekly anything serious has happened in side the engine or to the ECU. The most likely thing is a wiring error or not enough fuel.

 

make sure that the injector plugs are on the right way, i got them mixed up as mine were not labeled when i did my conversion. they do not go as you would logically think!
because of this i had the same problem.
the order it should be is: (starting cambelt side)
injector 1 : black / brown + brown wire
injector 2: red / brown + brown wire
inector 3: green / brown + brown wire
injector 4: yellow / brown + brown wire
BUT the idle control valve and injector plugs DO fit each other. i had injector 1 on 2, 2 on 3, 3 on 4 and 4 on idle control valve on idel control valve on injector one. the car did run at first but missfired like hell and wouldnt idle.....
got this confused as the wire for injector 4 is a lot longer that it should be it is just meant to sit inside the plastic case but i took that off when i rebuilt then engine. hope this helps mate

 

mate just done that then put cam senser red and blue colour wires to injecter 4 and injecter 4 to cam senser the car fired up but then cut out so swaped them back over car wont start but goes to fire up then cuts out

 

is your fuel pump going when its supposed to?

 

car now starts but wont idle

 

but wil it idle if you hold the revs? or is it lumpy?
if thats the issue,i had that problem and it was just a case of adjusting the idle screw but its an allen key that normally filled with wax so get a paperclip out and get scraping!
you are running the lambada sensor and maf sensor right?

 

idles if u hold the revs car has a lambada sensor, where is the idle screw

 

first off you have got the breather from the head either blocked off or connected to the crankcase breather right? as it wont idle if thats not done. if you look down at your coil pack, its like a lil metal pipe coming out of the side of the cylinder head, its meant to be joined up to the crankcase breather via a metal/rubber pipe that goes from there under the coil pack and the thermostat and round to the breather behind the exhaust manifold, if its not blocked of connected the engine will run too lean. a simple bit of hose and a bolt will be sufficient for blocking it.
if thats all done sort out the idle screw:
if you look at the throttle body, you have your linkage on your left and its in ahole above that.
Its the hole below where my finger is in this pic, sorry about the quality just nipped out and took it on my phone

 

checked the piped fella thats ok, think i mite have it all sorted, think injecter 4 is playing up nw and again so got a set coming.

cheers for your help

 

no probs glad i could help, hope it all works out soon!
