68k miles and car is slow to start each morning after sitting for the night.. (ambient temp 80deg)


It turns over properly and battery & voltage are fine. But it somewhat sputters a bit and 'chugs' .. until fully firing up. On occasion takes a 2nd push of the start button. Car runs 100% fine otherwise.


I did replace the plugs.. (due at 70k) ... but that wasn't it. Really thought it would be.


Other ideas?

 

I'd check the starter. Replaced mine a year ago.

 

Could be check valve in fuel system loosing prime

 

2nd for check valve....I am not sure about the Vantage but on many newer models this is built into the fuel filter assembly.

 

Not sure how to do this on the Aston, but I would check the fuel pressure at the injectors. Fuel rail not holding pressure? That's your problem. Rail pressure ok then move on to something else

 

This sounds exactly like what it is... I was going to guess maybe a fuel filter or something limiting initial injection.


Thanks!

 

Almost sounds like the fuel pump starting to go bad...
All answers given you make sense too...
Good luck
