Kango HDI injection failures

Hello forum members, I have a Renault Kangoo that starts and runs perfectly, but when I try to accelerate past 2000 RPM, the fault light on the dashboard comes on and the engine stalls, as if the control unit goes into emergency mode. Disconnecting the battery terminal restores everything to normal, as long as you don't accelerate hard. You have to drive it gently, otherwise the stalling happens again. If anyone knows where to start troubleshooting, I would appreciate it. It's a 2005 HDI model. Thanks to all.

Hi Turbine, to start, check the air filter to make sure it's not clogged. Good luck and regards.

Hey friend, how are you? Look, the check engine light comes on to warn of over-revving for the amount of fuel. Check the electric fuel pump to rule it out, but your problem must be in the pump itself. It has a high-pressure valve inside, and that's what's failing, since it has a micro-filter that gets clogged.

Saves could check the return of the injectors also give problems in those models.
