help please zetec
am putting a 1800 zetec in a mk3 escort. but it will start up straight away, maybe tickover high but ant tell as no exhaust on the car yet. but it
just wont rev up. i am using an inline fuel pump. a lot off the wiring has been cut out as used a mk6 escort loom. i was told i dont need the lamba by
some one but i think i may do now. i can not reuse the sensor as wires been cut to short. if i was not to have the sensor in would this stop the car
reving up? or could something else be ausing this or anyone had simllare problems. help please as i have a week left to finish the car for the first
meet this season. thanks ian.

Are your fuel lines in correctly, pump, fuel rail, regulator, return?
It will run the wrong way around just, start and idle but not much more.
You should not need Lambda feedback to rev when cold as the engine only goes into closed loop when the lambda is hot, if its missing then it goes in
to default mode. Best to piece the wires out really and include limp home may have rev restrictions and fueling will not be ideal.

i am using a inline pump from vw/audi gravity feed buy tank, is aprox 1/2" feed to pump so should think thats fine, filter is after pump. im
pretty sure i got my feed and return the right way round, have feed opiside to the regulator. am using a modeo 1800 injection rail with the escort
injectors. the return is just bodged in as ran out of copper, but return isnt that important is it? so you saying it should still rev up without a
lamdba sensor? it will if you only ever so slightly press throttle, but i mean very slightly press, soon as you give any sort of throtle it just goes
to die on me. the lamdba wires ant touch as was disconected from plug and the cut at sensor after. i may be wrong but im sure i disconected the sensor
when engine was in the mk6 and was ok. (but not 100% def)

i have just been looking up on the net. when took then engine out the mk6 it had a couple things bolted to the bulk head and i have put this in the
mk3 and i habe 2 or 3 plugs spare. i think that one maybe a egr solidnd. witch would tell it whento open and close, i have not put this in the mk3. am
think egr may have a big part to not reving up?

EGR is simply an emissions control system, providing the EGR valve remains closed it shouldn't stop the engine revving.
What actually happens when you try to rev it, does it just misfire badly or die completely?
