Fiesta 1.4tdci - Turbo not boosting - Rybot

Hi everyone.

I have a fiesta 1.4tdci MY07.
Have changed the injector seals (all 4). Since then the turbo will not boost. I have checked the turbo itself and I is fine. Had a mighty vac on the waste gate and that's working fine too. All the vacuum pipes and intake pipes are fine. The four inlet manifold seals are in a good clean condition and located correctly. There are no fault codes. All the injectors have gone back in the same order they came out and it's running fine... Just won't boost. Please help if you can. Thanks.

Poor connection on the boost sensor?

The same problem happened to my 1.4Tdci, after the injector seals were replaced by a mechanic. Ford looked at the car, but they could not find any fault codes. I then took my car to 2 Diesel specialists to find a solution, one in France and one in Croydon and they both told me that the injectors must have been damaged. Apparently they're extremely delicate on the 1.4Tdci. Speak to First Diesel Injection in Croydon, they know this problem very well and they are very helpful.

Thanks. Called them and they were very helpful indeed.

Four new injectors later, the car is now boosting as it should. Yippee!
