Renault Clio II: vehicle does not start
If the error mentioned above is detected, one possible cause could be a faulty seal on the high-pressure safety valve. Defective seals cause the fuel to be diverted from the high-pressure side into the pump housing and fed into the low-pressure circuit. This means that the fuel pressure required to start the engine – at least 150 bar – cannot be built up.
The safety valve, which is installed in the lower part of the high-pressure pump, must be unscrewed to check the seals. In the event of a repair, both seals must always be replaced. Since the vehicle manufacturer does not offer a spare part, the seals must be obtained from the pump manufacturer or the independent aftermarket.
