As i said itll run lean if the pump shits its self. You’ve a pressure fault. How the hell does a lamba sensor drop fuel pressure?
You priced a pump replacement like i said?
They where terrible in the mondeo and focus and knowing ford it’ll be the same in an smax.
How long and how much has your diagnosis cost so far? And why keep taking it different places? Any one can code it. And step one of any diag is a code read. Most places will knock the codes and f£%k it off. Which is why i said price a pump
Cos 100 quid diag vs 150 quid on putting a pump in I’d pick the pump to prove a point.
But keep cracking on ps a code reader that will do live data is about 30 quid.
