v12 vanquish low power flashing check engine light

[suzukidave]

Hi Guys,

jumped in my Vanquish today and started driving down the road, the car had very little power and the check engine light was flashing. Engine was running smooth, just low power. Ran the trouble codes with a cheapo scanner and it said multiple misfires on multiple cylinders. Car was running fine last week.
Any idea where to start?

Is this a Newport Pagnell Vanquish? If so, pose the question on the AMOC forum, as some very informed people on there:-

I had the same and it was failed fuel pumps. If the same, you can get fuel pumps for £50 rather than the £900 each Aston Martin charge!!

Ended up being one of the fuel pumps was bad. Replaced both with Delphi pumps. NAPA number FEO420. Here in the USA seem easiest to get.
