Sounded to me like it won't even crank over???
"When the engine is cold, there is a noticable lag/delay in time from when I turn the key before the engine turns over (approx 10 sec)"
If during this 10 sec it's cranking but not starting....there's alot of things that could cause this.
Check you fuel pressure first and foremost on the fuel rail. Alot of times the pressure valve on the fuel pump fails and allows the gas in the line to depresureize so the injectors are not primed. There's a fuel pressure regulator on the fuel rail too. Both can be check from the manual. Pressure vs time.
