I have a Fiat Punto 188 1.3 JTD Multijet and an issue, that brings me a headache since 2 years. The car is from 2005 and already has 180 000 miles down. Almost every time, the I fast accelerate from lower rotation in range from 800 - 2800 RPM, my car get a strong shock. Motor-Check lights up and since then you can not get higher rotation then 3000 RPM until you start the car new. After this I get two Error Messages: 1. Fuel pressure to low. 2. Fuel pressure to high. I already changes all the fuel pressure sensors and checked the high pressure pump at the car workshop. They have no idea what else could be wrong. Maybe you can help me.
