Ok so over the past couple weeks I’ve been able to narrow it down to a leaky fuel rail. Every time I open the driver door I hear the low pressure pump prime and the car has no trouble while running or driving (doesn’t stall no hesitation no weird misfires) so it can’t be high pressure either. After the car turns off I notice fuel rail pressure desired goes to 1450PSI and the fuel rail pressure begins to climb to that amount. Once it reaches over that desired pressure it seems so leak out around 500psi per hour until finally settling to around 50 psi while the car is not in used thus making a cold start difficult. The only time I smell fuel is when I’m doing a long crank. Is it safe to say that it’s most likely fuel rail if I were to tell my shop to look at it? Again no codes or anything just the long crank on only cold starts, starts right up othet wise
