hi guys converted my fiesta to zetec turbo but got a issue with running
it starts on the button has a little rev then cuts out will do this all day long but will not idle or rev up
any ideas

 

fuel pump not running with engine? or is it too lean because you still have same map/ecu as 1.6?

 

sorry wasnt very clear about conversion its a mk5 zetec s wiv cossie fuel pump 1.8zetec lump t3 turbo efi inlet not fiesta turbo zetec loom an unchip dastek ecu engine an management from same car only thing ive uprated is the fuel pump so in theroy it shud b over fueling ? as the last guy was running a fiesta turbo pump

 

It won't run rich with the bigger pump because the fuel pressure regulator will keep the fuel pressure the same. So it's a zetec inlet manifold and injectors? What ecu is it running? Is it still air mass sensing, if so what sensor have you used and where is it in relation to the turbo? Cheers

 

red top injectors
unichip ecu in conjunction with ofab
air mass sensor about 2inchs from turbo

 

try moving the air mass sensor about a foot or more away from the turbo, ive had a similar problem before with a car not idling with the air flow meter soo close. must be a cvh inlet manifold if you have got end feed injectors from a c20let? did you use an adaptor plate for your ehaust manifold or have you got a stainless manifold just out of interest.

 

the heads been tapped for t3 manifold which it has i fink its a ho inlet of a rs 1800

 

i tapped the head on my first zetec turbo and it leaked a bit mate! yours ok though? on my next one i made a plate the same as ferriday supply (was too tight to buy one and i work in a machine shop!) esc rs turbo manifold is good and tough though.
