hi iv have 53 doblo jtd will not start has a fault code of p0191 any help please thanks. ps had a new high press pump fitted as this was leaking.

For a Fiat

P0191 = Generic - Fuel Rail Pressure Sensor Circit Range / Performance

P0191 = Generic - Fuel Rail Pressure Sensor A Circit Range / Performance

With your "had a new high press pump fitted as this was leaking" there would appear to be a correlation. Did whoever relaced the pump reset any existing fault codes?

hi yes it was re set but still wont start .can it be the fuel rail press sensor .thanks

I would monitor the rail sensor as they are expensive and you have already fitted a pump, might be worth taking to a garage.
