Hi can anyone help me car starts runs for few seconds then cuts out?

carljsutton: Maybe check the fuel cutoff relay in the passenger footwell fuse box? (that's where is is on a db9 not sure where it is on DB7)

Throwing any codes? Rent a fuel pressure kit from auto zone and connect to the fuel line to check the pressure. Could be a weak fuel pump.

I have fault codes p0351-56 relating to ignition coils a-f

P0350 ignition coil primary / secondary circuit / open

P0340 camshaft sensor A circuit bank 1 or single sensor

I have checked cam sensors at sensor using scope both tra es look the same but hard to say as engine only runs for few seconds

Thanks in advance for any help

carljsutton: unless you've done it recently or know the service record for the car I would replace the cam sensors, coils, and plugs. I've got a DB9 and I don't have much trouble finding parts but I've never tried to look for a DB7.
