Yrv 1.3 turbo k3vet

Forum: 

Currently have a problem with a customers YRV Turbo it has me and 3 other techs confused, takes a lot of cranking to start when cold when warm it's fine. Have changed pre cat lambda due to being faulty and still no change and now no engine lights! It's like the car is choked up anyone had this problem before? Iv also done a ecu reset car has just started perfectly first time! Anyway if you could give me a hand by telling me if I'm looking in the wrong place ect would be brilliant! Autodata don't list any wiring information or a list of sensors what is a pain
Cheers in advance
