hi all maybe someone could help me on here .i have a ford fusion 1.4 tdci which i bought a month ago it was well under powered when i got it so got it remapped .it has gave it more power but it sounds like a transit di now just wondering if anybody would know if a 1.4 tdci would still run if the pump timiming was out as it had a new belt fitted just before i bought it i was thinking maybe whoever fitted it got it wrong and thats why it had no power in the first place.any help would be great thanks in advance
