Hi,
when I start the car the rpm jumps up and down ,it will not get steady
and there is weird clicking noise coming up ,
it seems like a battle to keep the engine running ,
Than the car just shuts down ,
Code p0087
Fuel rail / system pressure - too low

Car : jaguar s type v6 3.0L 2006 .

What's do you think the real problem is ?
