Problems when warm up

[Fperotti]

Dear all,

I have a 2.4T MFI, which I've been restoring the last eight years.

Nowadays, testing it on the street, things start quite well. Good response, no noises, no vibrations, etc. But, after 10 minutes of running aprox, the engine starts to fail just like a lack of fuel affect it.

I measured the pressure after the fuel pump and it seems to be ok at 13 - 15 psi even when the engine is warm.

My best guess is the thermostat attached to the injection pump but It would be great to hear other alternatives suggestions from you guys.

Thank you very much in advance,
Fernando.
