Dealer says the camshaft is worn and I need a new one for $1400.
Does this make sense? I'm no expert but it seems to me that if the camshaft was bad the car would run poorly all the time and not just take a few seconds longer to start.
Likely a defective fuel check valve with one being in the fuel pump and the other check valve being in the fuel pressure regulator. When the check valve leaks, all the fuel inside the fuel rail next to the fuel injectors that is supposed to stay there instead leaks back down into the gas tank. The slow start time is the time it takes the fuel pump to refill the fuel lines and fuel rail. The check valves are supposed to keep the fuel rail and fuel lines full for fast starts.
I'd start with the fuel pump which depending on how you buy it, may also include the fuel pressure regulator that sits on top of it. RockAuto Auto Parts
has them for around $160.
